CR6848 Datasheet Low Cost Green-mode Pwm Controller

Manufacturer: Chip-Rail

Overview: CR6848 Novel Low Cost Green-Power PWM Controller.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CR6848 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 PFM/CRM under light-load/zero-load conditions.

This can minimize standby power consumption and achieve green-power functions.
