DATA SHEET .onsemi. PWM Buck Regulator, Synchronous, Voltage Mode, High Performance, 65 V, 10 A Description FAN65008B 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 10 A. FAN65008B includes a 0.67% accurate reference voltage to achieve tight regulation. The switching frequency can be programmed from 100 k Hz to 1 MHz. To improve efficiency at light load condition, the device can be set to discontinuous conduction mode with pulse skipping operation. FAN65008B has dual LDOs to minimize power loss and integrated current sense circuit that provides cycle- by- cycle current limiting. This single phase buck regulator offers plete protection Features including Over current protection, Thermal shutdown, Under- voltage lockout, Over voltage protection, Under voltage protection and Short- circuit protection. FAN65008B uses onsemi’s high performance Power Trench® MOSFETs that reduces ringing in switching applications. FAN65008B integrates the controller, driver, and power MOSFETs into a thermally enhanced, pact 6 x 6 mm PQFN package. With an integrated approach, the plete DC/DC converter is optimized from the controller and driver to MOSFET switching performance, delivering a high power density solution.
