FAN65005A-GEVB: High Performance 65V, 8A Voltage Mode Synchronous PWM Buck Regulator Evaluation Board

The FAN65005A-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 8 A.

The FAN65005A-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 FAN65005A-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 FAN65005A-GEVB evaluation board uses ON Semiconductor’s high performance
POWERTRENCH® MOSFETs that reduces ringing in switching
applications. FAN65005A 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.
