Product Description

The MPM3570E is a high density, non-isolated DC-DC power module for space sensitive applications. The module offers a very compact solution to achieve 0.3A output current over a 4.5V to 75V wide input supply range, and can provide an adjustable output voltage from 1.0V to 5.0V via an external FB resistor (Default 3.3V output).

The MPM3570E integrates switching controller, power switches, inductors, a modest amount of input and output capacitors and all support components with an advanced 10×10×4.2mm size. And it requires a minimal number of standard external components. This compact solution significantly helps in system design and productivity by offering greatly simplified board design, layout and manufacturing requirements.

Ultra-high efficiency is achieved through the use of synchronous rectification and control techniques, especially under light-load condition. A 5μA shutdown quiescent current in full temperature range is good for battery-powered applications.

The module offers standard features, including of internal fixed soft-start, remote enable control and power OK indicator. It has fully integrated protections that include over-current protection, under-voltage lockout and thermal shutdown.
