Description
MARKING DIAGRAM
FAN65004C 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.

FAN65004C 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.

this data sheet.
®
FAN65004C uses onsemi’s high performance PowerTrench
MOSFETs that reduces ringing in switching applications.
FAN65004C 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.
