How to choose your own suitable LED Driver IC?
1, the market is mixed LED driver IC-AMC7150At that time, the AMC7150 was still good. I thought about it or mentioned it. It has a very important factor is the price, and the market price of less than 2 yuan is the reason you use it. The AMC7150 currently has dozens of IC models that can be directly replaced, and the price war cannot be avoided.
It can be selected in low-voltage 4-25V products with low design parameters, and the basic drive capability is designed to be less than 3W. For example, 1W string 3 or 3W1 LED design is stable.
Silan Semiconductor currently introduces new ICs, which are primarily aimed at driving the 6 LED market for 24V drives. The price is higher than the AMC7153 concessions to the European and American market IC, suitable for the design of 1-6 LED, input 6-25V input voltage, SOP8 package, mainly for the current low-end spotlight market.
This IC drives 1-7 1W LEDs. 92% efficiency, 6-28V voltage input range step-down driver application design. Compared with the previous two ICs, the biggest advantage is the package SOT23 size, line profile, in line with the current design requirements of most small-sized lamp cups.
Large resistance range current adjustment, can adjust the brightness of the potentiometer wide resistance range, such as the design of table lamps and other products need this time.
This IC is currently a good market response, but also SOT23 small size package, input 7-30V voltage step down constant current drive 1-7pscLED, the circuit is simple and practical. When designing Rs, it should be close to the IC to prevent the supply voltage from moving largely. This will affect the constant current effect.
The overall electronic material cost is slightly higher than the previous IC.
The LM3402 market has a good response. The input voltage range covers the entire automotive application field. The built-in MOS tube can have a maximum of 15 LEDs. 1-3 LEDs are a little expensive, and a price/performance ratio of 5 or more is very good. The current customer engineers who come in contact with them are highly valued, and they accept a relatively wide range of circuits that are concise and practical. They are among the leaders of many LED driver ICs in the country.
The LM3404 and LM3402 have the same circuit, but the difference is that the current can reach 1A, and the cost of driving 1-15pcsLED is higher.
The IC specifications listed above are built-in MOS tubes. The built-in MOS tube can simplify the circuit design, reduce the size, reduce the overall design cost, and reduce the failure rate. LED driver ICs that are more than 1A in size due to current IC process fabrication, cost, etc. require an external MOS transistor. In our daily product design often encounter high current design, such as 5W, 10W and other higher power design requirements, it can only choose the external MOS tube IC can. Next, several ICs will be recommended for comprehensive cost, which is convenient for the selection of engineers and friends.
The MAX16819/MAX16820 operate from a 4.5V to 28V input voltage range and have a 5V/10mA on-chip voltage regulator. The output current is regulated by the high-side current sense resistor. The dedicated PWM input (DIM) allows a wide range of pulsed brightness adjustments.
The MAX16819/MAX16820 are ideal for applications requiring a wide input voltage range. High-side current sensing and built-in current setting circuitry minimize the number of external components and provide ±5% accurate LED current. The hysteretic control algorithm ensures excellent input power rejection and fast response during load switching and PWM brightness adjustment. The MAX16819 has 30% of the inductor ripple current, while the MAX16820 has 10% of ripple current. These devices can operate at switching frequencies up to 2MHz, allowing the use of small components.
The MAX16819/MAX16820 operate over the -40°C to +125°C automotive temperature range and are available in a 3mm x 3mm x 0.8mm, 6-pin TDFN package.
Personally recommend 200-500Hz PWM gray frequency adjustment, 1-6pcsLED series maximum 25W product design, recommend about the price of about 0.5 US dollars.
LM3401 is an external MOS high-Power LED Driver introduced by National Semiconductor. It can design a driving current within 3A. The input voltage is up to 35V, and more than 10 LEDs can be connected in series.
The MAX16802A/B are high-brightness (HB) LED driver control ICs that contain all the circuitry needed to design a wide input range LED driver for general lighting and display applications. Suitable for low input voltage (10. 8VDC to 24VDC) LED drivers. When precision LED current adjustment is required, on-chip error amplifiers and a 1% accuracy reference can be used. A wide range of brightness adjustment can be achieved with low frequency PWM brightness adjustment.
The MAX16802 features an input undervoltage lockout (UVLO) feature that sets the input startup voltage and ensures proper operation in the event of a power supply drop. The MAX16802 has an internal high bootstrap undervoltage lockout circuit.
This simplifies the design of offline LED drivers. The MAX16802 does not have this bootstrap circuit and can be biased directly from a +12V supply. The internally trimmed 262kHz fixed switching frequency allows for the optimal selection of magnetics and filter components for a compact, cost-effective LED driver.
The MAX16802A has a maximum duty cycle of 50% and the MAX16802B has a maximum duty cycle of 75%. These devices are available in an 8-pin μMAX® package and operate over the -40°C to +85°C temperature range.
Personally recommend 200-500Hz PWM gray frequency adjustment, 1-6pcsLED series maximum 50W product design, about the price of about 1. 4 US dollars.
The MAX16818 pulse-width modulation (PWM) LED driver controller is available in a compact package that provides high output current with minimal external components. The MAX16818 is well suited for synchronous and non-synchronous buck topology, as well as boost, buck-boost, SEPIC, and buckLED driver architectures. Fast LED transient currents up to 20A/μs and brightness adjustment frequency of 30kHz can be achieved.
The device uses average current mode control and optimizes the use of MOSFETs with optimal charge and on-resistance characteristics to minimize the need for external heatsinks even when the output LED current is as high as 30A. True differential detection technology allows precise control of the LED current. Wide-range brightness adjustment can be easily achieved with an external PWM signal. An internal voltage regulator with a simple external bias device allows the device to operate over a wide input voltage range of 4.75V to 5.7V or 7V to 28V. The wide switching frequency range can be as high as 1.5 MHz, allowing the use of small inductors and capacitors.
The MAX16818 has a clock output with a 180° phase delay and can be used to control another LED driver operating out of phase to reduce input and output filter capacitor size and reduce ripple current. The MAX16818 also offers programmable hiccup overcurrent, overvoltage, and overtemperature protection. The MAX16818ETE+ is rated to operate over the extended temperature range (-40°C to +85°C), while the MAX16818ATE+ operates over the automotive temperature range (-40°C to +125°C). The LED driver controller is available in a lead-free, 0.8mm thick, 5mm x 5mm 28-pin TQFN package with exposed pad.
High-current LED drive controller IC, output current up to 30A, it is recommended to design 50-300W super power portable LED projector, LCDTV and display backlight, front panel projector/rear projection TV, car, bus/truck exterior light, car emergency lighting With symbol lights, etc. products. Sample application prices are around $3.
