Description

The EVM3690-50A-BF-00A evaluation board is designed to demonstrate the capabilities of the MPM3690-50A, a fully integrated, highefficiency, synchronous, dual 25A output current (IOUT), step-down power module. The MPM3690-50A adopts internally compensated constant-on-time (COT) control to provide fast transient response and ease loop stabilization. The operating frequency can be set between 400kHz and 1MHz by connecting a resistor between fSET and AGND. Refer to the MPM3690-50A datasheet for more detailed information. It is recommended to read the datasheet for the MPM3690-50A prior to making any changes to the EVM3690-50A-BF-00A.
