The SSL2101 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from rectified mains. It is designed to drive LED devices. The device includes a high-voltage power switch and a circuit to allow start-up directly from the rectified mains voltage. Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer.
SSL2101主要特性:
Easy migration to existing lighting control infrastructure, triac and transistor dimmers
Supports majority of available dimming solutions
Valley switching efficiency is optimized by built-in dedicated circuitry
Built-in demagnetization detection
The IC has built-in OverTemperature Protection (OTP)
Short-Winding Protection (SWP) and OverCurrent Protection (OCP)
