SP201 Offline Current Mode PWM Controller

SP201 is a high performance current mode PWM controller for offline flyback converter applications. The IC has built-in General Primary Side CC control, which simplifies isolated power supply design that requires CC regulation of the output. In SP201, PWM switching frequency with shuffling is fixed.

SP201 Features

* General Primary Side Constant-Current (CC) Control Supports DCM and CCM Operation

* ±5% CC Regulation, ±1% CV Regulation with Fast Dynamic Response

* CC Algorithm Compensates for Line Variation and Transformer Inductance Tolerance

* Less than 75mW Standby Power for sub 30W Applicat
