1. General description
The SSL2103 is a Switched Mode Power Supply (SMPS) controller IC that operates in
combination with a phase cut dimmer directly from the rectified mains. It is designed to
drive LED devices. The device includes a circuit to allow direct start-up from the rectified
mains voltage.
For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.
• SSL2101: fully integrated LED driver for lamps up to 10 W
• SSL2102: fully integrated LED driver for lamps up to 25 W
• SSL2103: gives the application designer flexibility to:
– Use an external power switch to allow the IC to provide any power
– Use an external bleeder transistors to provide extended dimmer interoperability
2. Features and benefits
Easy migration to existing lighting control infrastructure
Supports most available dimming solutions
Optimized efficiency with valley switching managed by a built-in circuitry
Demagnetization detection
OverTemperature Protection (OTP)
Short-Winding Protection (SWP) and OverCurrent Protection (OCP)
Internal V
CC
generation allowing start-up from the rectified mains voltage
Natural dimming curve by logarithmic correction, down to 1 %
Suitable for flyback and buck applications
3. Applications
SSL applications with various power requirements
LED modules such as LED spots and down-lights
LED strings suitable for retail displays, etc.
