ROHM Semiconductor BD9F500QUZ-EVK-001 Evaluation Board, available now from Mouser, is a demonstration platform for the BD9F500QUZ Nano Pulse Control Synchronous Buck DC-DC Converter with integrated power MOSFETs. The board features a 4.5V to 36V input voltage range, a 0.6V to 14V output voltage range, and a maximum output current of 5A. The device's Constant On-Time control system allows fast transient response, and the Light Load Mode control improves efficiency in light-load conditions.


The board features a reference circuit based on the BD9F500QUZ together with all needed support components. Test posts provide access to all key signals. Jumpers enable the user to modify the switching frequency, maximum output current and choose between Light Load and Fixed PWM operation modes.
