Monolithic Power Systems (MPS) MPM3698 Scalable Power Modules
Monolithic Power Systems (MPS) MPM3698 Scalable Power Modules are fully integrated, 16V, single peak 120A or dual peak 80A + 40A power modules with a digital interface. The MPS MPM3698 modules integrate a VR14-compatible dual-loop digital multi-phase controller and three sets of driver MOSFETs and inductors. These modules offer a wide operating input voltage range, digital control, and flexible phase assignment, making them highly adaptable for different power requirements. MPM3698 modules are available in a thermally enhanced BGA (15mm x 30mm x 5.18mm) package.
Each phase of the MPM3698 power modules can provide up to 40A of peak output current (IOUT) and 30A of continuous IOUT. The outputs of the three phases can be paralleled to provide up to 120A of peak IOUT or 90A of continuous IOUT. The digital interface allows for flexible, digital configurations and monitoring of key parameters. The MPM3698 provides on-chip non-volatile memory (NVM) to store and restore device configurations. Device configurations and fault parameters are easy to configure and monitor. Featuring MPS's proprietary digital, multi-phase nonlinear control scheme, these devices provide ultra-fast transient response with minimal output capacitance. With only one power loop control method for both steady state and load transient, the power loop compensation is very easy to configure.
