Power module with integrated inductor
14 November 2018
Power Electronics / Power Management
The MPM3570E is a high-density, non-isolated DC-DC power module for space sensitive applications. It offers a very compact solution to achieve 0,3 A output current over a 4,5 V to 75 V wide input supply range, and can provide an adjustable output voltage from 1,0 V to 5,0 V via an external FB resistor (default 3,3 V output).
The chip, which is made by Monolithic Power Systems, integrates switching controller, power switches, inductors, a modest amount of input and output capacitors, and all support components in a 10 x 10 x 4,2 mm size, and 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.
High efficiency is achieved through the use of synchronous rectification and control techniques, especially under light-load condition. A 5 μA shutdown quiescent current in full temperature range is good for battery-powered applications.
The module offers standard features including internal fixed soft-start, remote enable control and power OK indicator. It has fully integrated protections that include over-current, under-voltage lockout and thermal shutdown.
