The TPS560430 is an easy to use synchronous step-down DC-DC converter capable of driving
up to 600 mA. With a wide input range of 4 V to 36 V, the device is suitable for a wide range of
applications from industrial to automotive for power conditioning from an unregulated source.
The TPS560430 has 1.1-MHz and 2.1-MHz operating frequency versions for either high
efficiency or small solution size. The TPS560430 also has FPWM (forced PWM) version to achieve
constant frequency and small output voltage ripple at light load. Soft-start and compensation
circuits are implemented internally which allow the device to be used with minimized external
The device has built-in protection features, such as cycle-by-cycle current limit, hiccup
mode short-circuit protection, and thermal shutdown in case of excessive power dissipation. The
TPS560430 is available in a low profile 6-pin SOT-23-6 package.
