The MP157GS-P from Monolithic Power Systems is a versatile offline AC/DC regulator delivering up to 6 W with an integrated power switch rated to 500V breakdown. It supports Boost, Buck, Buck-Boost, and Flyback topologies, enabling both isolated and non-isolated designs. Built-in protections include open loop, over load, over temperature, over voltage, short circuit, and UVLO, with frequency control and soft start. Housed in an 8-SOIC package.
- Integrated switch reduces external component count and simplifies layout.
- Multi-topology flexibility (Boost, Buck, Buck-Boost, Flyback) supports diverse design needs.
- 500V breakdown rating enables robust offline operation.
- Comprehensive fault protection improves system reliability.
- Wide -40°C to 125°C junction range suits demanding environments.
Compact Auxiliary Power Supplies
With 6 W output and a 500V breakdown rating, the MP157GS-P suits low-power auxiliary rails where an integrated switch reduces BOM count.
Isolated Flyback Bias Rails
The flyback topology option provides galvanic isolation for bias and housekeeping supplies in larger systems.
Non-Isolated Buck Regulation
Buck operation supports direct step-down regulation for control circuitry in space-constrained boards.
Buck-Boost and Boost Rails
Flexible topology support lets the same device address step-up or step-up/down requirements across platforms.
Harsh-Environment Electronics
A -40°C to 125°C junction temperature range supports reliable operation in demanding thermal environments.
