PQFN35 6x6 CASE 483BE
Description 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.
FAN65004C 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.
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.
