LTM8042 µModule Boost LED Driver & Current Source

Analog Devices LTM8042 µModule Boost LED Driver and Current Source is specifically designed to drive LEDs up to 1A. The LTM8042-1 drives up to 350mA. The device combines a boost power topology with a unique current loop to operate as a constant-current source. The PWM input provides 3000:1 LED dimming and 10:1 analog dimming by a single resistor or analog voltage applied to the CTL pin. The Analog Devices LTM8042/LTM8042-1 has an uninterrupted current path between input and output. It's intolerant to a short-circuit or overload from the output to ground.

IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.
