Automotive, 4V to 36V, 0.6A synchronous step-down SIMPLE SWITCHER® power converter

The TPS560430-Q1 is a wide-VIN, easy to use synchronous buck 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 automotive applications for power conditioning from an unregulated source.

TPS560430-Q1 operates at 2.1-MHz switching frequency to support use of relatively small inductors for an optimized solution size. It has Eco-mode version to realize high efficiency at light load and FPWM version to achieve constant frequency, 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-Q1 is available in SOT-23-6 package.
