UM10477: SSL2101 120 V (AC) flyback task light 20 V/450 mA driver board
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)
The IC has internal VCC generation that allows start-up from rectified mains voltage
Natural dimming curve by logarithmic correction
SSL2101应用:
The SSL2101 is suitable for different power requirements, these include:
Retro-fit lamps, e.g. GU10, up to a maximum of 10 W
LED modules, separate power supplies, e.g. LED spots, down-lights, up to a maximum of 15 W
LED strings, e.g. retail display, up to a maximum of 15 W
Mains isolated LED drivers up to 10 W to 15 W (flyback topology)
Non mains isolate LED drivers (buck topology) with a maximum peak current of 900 mA and continuous LED current below 450 mA
LED lamps 1 W to 10 W (flyback) or 450 mA (buck)
