The EVM3698-BH-02A evaluation board is designed to demonstrate the capabilities of both the MPM3698 and MPM3699. Each power module can achieve between 4.5V and 16V of input voltage (V_IN), and between 0.3V and 5.5V of adjustable output voltage (V_OUT) with PMBus and AVSBus interfaces. These boards can provide up to 440A of peak output current (I_OUT) or 330A of continuous I_OUT.

The MPM3698 features MPS’s proprietary digital, multi-phase, nonlinear control scheme to provide fast transient response to load transient with minimal output capacitors. With only one power loop control method for both steady state and load transient, the power loop compensation is very easy to configure.

The MPM3699 offers many features to simplify system design. Each phase of the MPM3699 has individual tri-state pulse-width modulation (PWM) inputs to work with the MPM3698. The MPM3699 also has a separate accurate current sense and temperature output to report the inductor current (I_L) and junction temperature (T_J) of each phase.

It is recommended to read the datasheet for both the MPM3698 and MPM3699 prior to making any changes to the EVM3698-BH-02A.
