M-Power2B series
A multi chip power device for a Multi-Oscillated Current Resonant type Converter
Features
■
・Power efficiency keeps high from a light load to a rated load.
・Low noise is achieved because of soft switching technique.
・Easy to design high reliability SMPS due to various
protection function.
・External components drastic reduction from former-model.
Applications
■
・SMPS for AV equipments (LCD-TV and PDP etc.)
・SMPS for OA equipments (Copier etc.)
