TPS560430YQDBVRQ1

TPS560430-Q1 is an easy-to-use wide VIN synchronous buck converter capable of driving load currents up to 600mA. The device features a wide input range of 4V to 36V, suitable for automotive applications, enabling power regulation from unregulated sources. TPS560430-Q1 operates at a switching frequency of 2.1MHz, supporting the use of relatively small inductors for an optimized solution size. It is available in an Eco-mode version for high efficiency at light loads, and an FPWM version for constant frequency and low output voltage ripple across the full load range. Soft-start and compensation circuits are implemented internally, minimizing the number of external components required. The device features built-in protection functions, including cycle-by-cycle current limiting, hiccup mode short-circuit protection, and thermal shutdown in the event of excessive power dissipation. The TPS560430-Q1 is available in a SOT-23-6 package.
