Diodes Incorporated AP3776 AC/DC Power Supply Controller
Diodes Inc. AP3776 AC/DC Power Supply Controller is designed for battery charger and adapter applications. The AP3776 can meet the "Super Star" charger criteria by using less than 10mW on standby mode. Pulse frequency modulation (PFM) is used which makes the AP3776 suitable for discontinuous conduction mode (DCM) flyback power supplies. Additionally, accurate constant voltage (CV) and constant current (CC) are available without using an optocoupler. When the AP3776 is used with the AP4241, APR343, or APR3415, good under-shoot performance and higher conversion efficiency can be achieved.
