The Monolithic Power Systems MP155GS-Z is a non-isolated offline switcher supporting Boost, Buck, Buck-Boost, and Flyback topologies with an integrated power switch. It delivers up to 4 W with a 500V breakdown rating and operates from a Vcc supply of 5.3V to 5.6V. Protection includes open loop, over load, over temperature, and short circuit. Housed in an 8-SOIC package, it operates from -40°C to 125°C junction temperature.
- Multi-topology support (Boost, Buck, Buck-Boost, Flyback) adds design flexibility.
- Integrated switch reduces external component count.
- 500V breakdown rating suits offline non-isolated applications.
- Multiple fault protections (open loop, over load, over temperature, short circuit) improve reliability.
- Compact 8-SOIC package for space-constrained designs.
Compact Non-Isolated Supplies
The MP155GS-Z supports Buck, Boost, Buck-Boost, and Flyback topologies in a non-isolated configuration, delivering up to 4 W for compact direct-coupled designs.
Bias & Housekeeping Rails
A 500V breakdown rating and 5.3V to 5.6V Vcc supply make this device suitable for offline bias rails in larger systems.
Smart Home & IoT Devices
Open loop, over load, over temperature, and short circuit protection support reliable operation in connected electronics.
Industrial Control Boards
The 8-SOIC package and -40°C to 125°C junction range enable use in space-constrained industrial control designs.
