onsemi Fixed-Frequency Monolithic Buck Switching Regulator Evaluation Board Switching Regulator for NCV890101 [NV890101MWTXGEVB]; 248-3940

The ON Semiconductor NCV890101 demonstration board provides a convenient way to evaluate a high-frequency buck converter design. No additional components are required, other than dc supplies for the input and enable voltages. An external clock can be used to synchronize the switching frequency

and the board also provides a synchronization

output, enabling it to be used as a master. It is configured for a 3.3 V output with a 2 MHz switching frequency and a 1.2 A maximum output current, over the typical 4.5 V to 18 V automotive input voltage range. In addition, the board regulates up to 36 V thanks to switching frequency foldback.
