Diodes Inc AP3776BMTR-G1 AC/DC power supply controller is designed for battery charger and adapter applications. The AP3776BMTR-G1 can meet the "Super Star" charger criteria by using less than 10mW on standby mode. Pulse frequency modulation (PFM) is used which makes the AP3776BMTR-G1 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 AP3776BMTR-G1 is used with the AP4241, APR343, or APR3415, good under-shoot performance and higher conversion efficiency can be achieved.
