CR6848 - Chip-Rail

CR6848 Low Cost Green-Mode PWM Controller

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 a.
