Monolithic Power Systems' MPM3570E is a high density, non-isolated DC/DC power module for space-sensitive applications. It offers an ultra-compact solution that achieves 0.3 A output current over a wide 4.5 V to 75 V input supply range and can provide an adjustable output voltage from 1.0 V to 12 V via an external FB resistor (default 3.3 V output).
The MPM3570E integrates a switching controller, power switches, inductors, a modest amount of input and output capacitors, and supporting components in a small package size. This compact solution helps the system design and production significantly by offering an ultra-simplified board design, layout, and manufacturing requirements. Ultra-high efficiency is achieved through synchronous rectification and control techniques, especially under light-load conditions. A shutdown quiescent current of 25 µA in the full temperature range is optimal for battery-powered applications.
The MPM3570E features internal fixed soft-start (SS), remote enable (EN) control, and power OK indication (POK). Full protection features include overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown. The power module requires a minimal number of external components and is available in a compact LGA8 (10 mm x 10 mm x 4.2 mm) package.
