3 Description

The TPS560430 is an easy to use synchronous stepdown

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.
