MAX25603AUI/V+

MAX25603AUI/V+ is a synchronous, automotive four-switch buck-boost LED controller for combination head lights. The controller regulates the LED current for LED string voltages from 0V to 60V. The MAX25603 can be used as a seamless buck-boost LED driver for applications that require an efficient buck-boost LED driver with synchronous rectification. The MAX25603 is ideal for high-power applications that require a current source with PWM dimming capability. The device provides seamless transition between buck, boost, and buck-boost modes depending on the ratio of input to output voltage. The MAX25603 is ideal for LED driver applications in automotive, industrial, and other LED lighting applications. Suitable for combination automotive head lamps applications.
