CR6853T PWM Controller IC DIP-8

Its CR6853T highly integrated, low-cost current mode PWM controller that is perfect for offline AC-DC fly-back converter Applications requiring a minimal amount of current flow. Under light-load/zero-load conditions, the IC modifies the operating frequency and automatically enters the PFM/CRM (Cycle Reset Mode), using external resistors. Its used in Switching AC/DC Adapter, power switching circuits, Battery charger and open frame switching power supply.
