SP201 Overview
Description
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.
Key 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 Application
- Current Mode Control
