FAN65004B is a wide VIN highly efficient synchronous buck regulator, with integrated high side and low side power MOSFETs. The device incorporates a fixed frequency voltage mode PWM controller supporting a wide voltage range from 4.5 V to 65 V and can handle continuous currents up to 6 A. FAN65004B includes a 0.67% accurate reference voltage to achieve tight regulation. The switching frequency can be programmed from 100 kHz to 1 MHz.

This single phase buck regulator offers complete protection features including Over current protection, Thermal shutdown, Under−voltage lockout, Over voltage protection, Under voltage protection and Short−circuit protection. This device is available in a compact 6 x 6 mm PQFN package.
