( DataSheet : www.DataSheet4U.com ) MITSUMI Secondary Control for Energy-Saving AC Adaptor MM1548 Secondary Control for Energy-Saving AC Adaptor Monolithic IC MM1548 Outline This IC is secondary control on AC adaptors that have energy-saving mode. The energy-saving mode function operates when charging is completed or when the set is unplugged, thus greatly reducing AC adaptor power consumption. When a set is connected, normal mode automatically starts and charging starts. Compared to the conventional MM1529, this IC is smaller and has fewer external components. Features 1. Automatic switching between energy-saving mode and normal mode 2. Current consumption (energy-saving mode) 60µA 3. Current consumption (normal mode) 1.5mA 4. Uses one photocoupler to control oscillator primary side.
