Description

The TPS560430-Q1 is a wide-VIN, easyto use synchronous buck converter capable of driving up to 600-mA load current. With a wide inputrange of 4 V to 36 V, the device is suitable for a wide range of automotiveapplications for power conditioning from an unregulated source.

TPS560430-Q1 operates at 2.1-MHz switching frequency to support use ofrelatively small inductors for an optimized solution size. It has Eco-mode version to realize highefficiency at light load and FPWM version to achieve constant frequency, small output voltageripple over the full load range. Soft-start and compensation circuits are implemented internallywhich allows the device to be used with minimum external components.

The device has built-in protection features, such as cycle-by-cycle current limit, hiccupmode short-circuit protection, and thermal shutdown in case of excessive power dissipation. TheTPS560430-Q1 is available in SOT-23-6 package.
