Classic Charger

The classic chargers are mobile phone chargers with a mobile phone charger output based on the USB Type-A port to Mini Type-B ports. Commercially available chargers come in different types: feature-rich such as low standby power chargers (<10mW standby power) and value-focus chargers (<75mW industry standard stand-by power). 

We offer various cost-effective PSR controllers, without optocoupler in the secondary side regulation, suitable for charger applications up to 25W with external switch devices. For cost consideration of classical mobile phone chargers, various PSR switchers are offered with either Bipolar Junction Transistor (BJT) or Metal-Oxide-Semiconductor (MOS) as switch device co-packaged with PSR controller die in SO-7 or SO-8 package.
