JWH6346
The JWH6346 is a synchronous buck regulator controller. Operating with an input range of 6V~75V, the JWH6346 adopts voltage mode control and provides high efficiency, excellent transient response, and high DC output accuracy needed for low output voltage, high current, PC system power rail and similar POL power supply in digital consumer products.
The JWH6346 guarantees robustness with thermal protection, short-circuit protection, over current protection and VCC under voltage protection.
The JWH6346 is available in QFN3.5X4.5-20 package, which provides a compact solution with minimal external components.
