FAN65005A

DATA SHEET www.onsemi.com Synchronous PWM Buck Regulator, Voltage Mode, High Performance, 65 V, 8 A FAN65005A PQFN35 6x6 CASE 483BE Description FAN65005A 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 8 A. FAN65005A includes a 0.67% accurate reference voltage to achieve tight regulation. The switching frequency can be programmed from 100 kHz to 1 MHz. To improve efficiency at light load condition, the device can be set to discontinuous conduction mode with pulse skipping operation. FAN65005A 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 complete protection features including Over current protection, Thermal shutdown, Under−voltage lockout, Over voltage protection, Under voltage protection and Short−circuit protection. FAN65005A uses onsemi’s high performance PowerTrench® MOSFETs that reduces ringing in switching applications. FAN65005A integrates the controller, driver, and power MOSFETs into a thermally enhanced, compact 6 x 6 mm PQFN package. With an integrated approach, the complete DC/DC converter is optimized from the controller and driver to MOSFET switching performance, delivering a high power density solution. MARKING DIAGRAM ...
