Texas Instruments  PS560430YQDBVTQ1

The TPS560430-Q1 is an easy to use synchronous step-downDC-DC converter capable of driving up to 600-mA load current. With a wide input range of 4 V to 36V, the device is suitable for a wide range of applications from industrial to automotive for powerconditioning from an unregulated source.

The TPS560430-Q1 is 2.1-MHz operating frequencyfor small solution size. The TPS560430-Q1 also has FPWM (forcedPWM) version to achieve constant frequency and small output voltage ripple over the full loadrange. Soft-start and compensation circuits are implemented internally which allows the device tobe used with minimum external components.

The device has built-in protection features, such as cycle-by-cycle current limit, hiccupmode short-circuit protection, and thermal shutdown in case of excessive power dissipation. TheTPS560430-Q1 is available in SOT-23-6 package.
