The TPS560430 is an easy to use synchronous step-down DC-DC converter capable of drivingup to 600-mA load current. With a wide input range of 4 V to 36 V, the device is suitable for awide range of applications from industrial to automotive for power conditioning from an unregulatedsource.
The TPS560430 has 1.1-MHz and 2.1-MHz operating frequency versions for either highefficiency or small solution size. The TPS560430 also has FPWM (forced PWM) version to achieveconstant frequency and small output voltage ripple over the full load range. Soft-start andcompensation circuits are implemented internally which allows the device to be used with minimumexternal 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 is available in SOT-23-6 package.
