H6850NF Description
The H68 50 is a highly integrated low cost current mode PWM controller, which is ideal for small power cur rent mode of of fline AC-DC fly- back converter applic ations. Making use of external resistors, the IC changes the operating frequency and automatically enters the PFM/CRM ( Cycle Reset Mode) und er light-load/zer o-load conditions. This can minimize standby power consumption and achieve powe rsaving functions.
