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)
3. Current consumption (normal mode)
4. Uses one photocoupler to control oscillator primary side.
5. One photocoupler is used to control rated voltage and rated current and switching between energy-saving
and normal modes.
