Available tools

The FAN6500xx-GEVB evaluation board 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. 

The FAN6500xx-GEVB evaluation board 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. 

The FAN6500xx-GEVB evaluation board 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. 

The FAN6500xx-GEVB evaluation board uses ON Semiconductor’s high performance POWERTRENCH® MOSFETs that reduces ringing in switching applications. FAN65004B integrates the controller, driver, and power MOSFETs into a thermally enhanced, compact 6 × 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.
