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.

MAX25603 Automotive 4-Switch LED Controller

Analog Devices MAX25603 Automotive 4-Switch Buck-Boost LED Controller is designed for multifunction automotive combination headlamps. The MAX25603 regulates the LED current for LED string voltages from 0V to 60V. The Automotive Controller is ideal for high-power applications requiring a current PWM dimming capability source. Additionally, the device is used as a seamless buck-boost LED driver for applications that require an efficient buck-boost LED driver with synchronous rectification.
