Description
The GR1215 is a high performance primary side feedback controller with PFM operation for flyback converter. It minimizes the components counts and is available in a tiny SOT-26 package. Those make it an ideal design for low cost application. It provides functions of low startup current, green-mode power-saving operation, VCC over-voltage protection, and FB pin abnormal conditions sensing to prevent the circuit being damaged from the abnormal conditions.
Applications
l Mobile Phone Charger
l Lower Power AC/DC Adapter
