The TPS560430 is an easy to use synchronous step-down DC-DC converter capable of driving
up to 600-mA load current. 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 over the full load range. Soft-start and
compensation circuits are implemented internally which allows the device to be used with minimum
external components.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 SOT-23-6 package.
