The Monolithic Power Systems MP158GJ-Z is a non-isolated offline converter supporting Boost, Buck, Buck-Boost, and Flyback topologies in a TSOT-23-5 package. It integrates the switch, delivers up to 2 W, and operates from a 5.3V to 5.6V Vcc supply with a 500V breakdown rating. Soft start and comprehensive fault protection make it a versatile choice for compact offline designs.
- Multi-topology support (Boost, Buck, Buck-Boost, Flyback) for design flexibility.
- Integrated switch reduces external component count.
- Soft start limits inrush stress during power-up.
- Comprehensive fault protection including OVP, OTP, and short circuit.
- Compact TSOT-23-5 package saves board space.
Multi-Topology Offline Conversion
Support for Boost, Buck, Buck-Boost, and Flyback topologies gives designers flexibility across non-isolated offline designs.
Low-Power Bias Supplies
The 2 W output and integrated switch suit compact auxiliary and bias rails.
Compact Consumer Electronics
The TSOT-23-5 package and soft start feature enable space-constrained non-isolated power stages.
Industrial Control Modules
A -40°C to 125°C junction range and broad fault protection support reliable operation in control electronics.
