FAN65004B
High Performance 65 V, 6 A
Voltage Mode Synchronous
PWM Buck Regulator
Description www.onsemi.com 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. To improve efficiency at light load condition, the
device can be set to discontinuous conduction mode with pulse
skipping operation.
FAN65004B 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.
FAN65004B uses ON Semiconductor’s high performance
PowerTrenchВ® MOSFETs that reduces ringing in switching
applications. FAN65004B integrates the controller, driver, and power …
