reference design / application evaluation kit
-
- evaluation board - bd9p208muf-tsb-001
this evaluation board was developed for rohm's single 2.2mhz buck dc/dc converter bd9p208muf-c. bd9p208muf-c is a current mode synchronous buck dc/dc converter with integrated power mosfets. the bd9p208muf-c accepts a power supply input range of 3.5v to 40v and generates a maximum output current of 2a. bd9p208muf-c generates an output voltage range of 0.8v to 8.5v using external resistors.
