TPS560430XDBVR General Description

The TPS560430XDBVR is a synchronous buck converter designed to efficiently step down voltage in various electronic systems, particularly in applications where high efficiency and compact size are essential.

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.
