The MP163BGSE-33-Z from Monolithic Power Systems is a non-isolated offline regulator with an integrated switch rated to 700V breakdown. It supports Boost, Buck, Buck-Boost, and Flyback topologies, delivering up to 4 W at a 28kHz switching frequency. Housed in a 16-SOIC package, it includes enable, soft start, current limiting, over load, and short circuit protection across a -40°C to 125°C junction temperature range.
- Integrated 700V switch reduces external component count and simplifies offline designs.
- Four selectable topologies (Boost, Buck, Buck-Boost, Flyback) provide design flexibility for varied output requirements.
- Built-in current limiting, over load, and short circuit protection enhance reliability under fault conditions.
- Soft start and enable control support predictable power-up sequencing.
- Wide -40°C to 125°C junction temperature range suits demanding thermal environments.
Low-Power Offline Bias Supplies
The 4 W power rating and 700V breakdown voltage make this device well suited for auxiliary bias supplies that draw from a rectified AC line. The integrated switch simplifies the design while the 28kHz switching frequency keeps switching losses manageable in a compact 16-SOIC footprint.
Non-Isolated Buck Regulation
For direct-coupled step-down regulation from an offline rail, the Buck topology provides a straightforward path. Soft start and enable control allow predictable power-up sequencing, while current limiting and short circuit protection guard the load during fault conditions.
Buck-Boost and Boost Auxiliary Rails
When the output voltage must sit above or below the input, the Buck-Boost and Boost topologies offer flexibility. The 5.4V to 6V Vcc supply and 5.3V start-up threshold support reliable startup across the operating range.
Flyback for Galvanic Applications
Although configured for non-isolated operation, the Flyback topology option supports designs requiring a transformer-coupled stage. Over load and short circuit protection help maintain safe operation in space-constrained 16-SOIC assemblies.
