RS2051 Datasheet (PTC) - Green-Mode PWM Controller

RS2051, Green-Mode PWM Controller

The RS2051 is a highly integrated low cost current mode PWM controller, which is ideal for small power current mode of offline AC-DC fly-back converter applications.

Making use of external resistors, the IC changes the operating frequency and automatically enters the Burst/CRM (Cycle Reset Mode) und
