FAN65004B Datasheet | onsemi

Description 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 k Hz 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 plete protection features including Over current protection, Thermal shutdown, Under- voltage lockout, Over voltage protection, Under voltage protection and Short- circuit protection. FAN65004B uses onsemi’s high performance POWERTRENCH® MOSFETs that reduces ringing in switching applications. FAN65004B integrates the controller, driver, and power MOSFETs into a thermally enhanced, pact 6 x 6 mm PQFN package. With an integrated approach, the plete DC/DC converter is optimized from the controller and driver to MOSFET switching performance, delivering a high power density solution.
