FAN65008B
High Performance 65V, 10A
Voltage Mode Synchronous
PWM Buck Regulator
Description www.onsemi.com 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 kHz 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 complete protection features
including Over current protection, Thermal shutdown, Under-voltage
lockout, Over voltage protection, Under voltage protection and
Short-circuit protection.
FAN65008B uses ON Semiconductor’s high performance
PowerTrenchВ® MOSFETs that reduces ringing in switching
applications. FAN65008B integrates the controller, driver, and power …
