SSL2103: SMPS controller IC for dimmable LED lighting
SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LED lighting applications. It is an extension of the NXP SSL2101/SSL2102 product platform, allowing easy design of derivative applications.
When used in combination with a phase cut dimmer connected directly to a rectified mains, it provides dimmability to the application.
In dimmer applications, 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 permitting the:
control of an external power switch to allow the IC to provide any power
control of external bleeder transistors to provide extended dimmer interoperability
The device includes a circuit that allows start-up directly from the rectified mains voltage.
Easy migration to existing lighting control infrastructures, TRIAC and transistor Dimmers
Compatible with most dimming solutions
Optimized efficiency with valley switching managed by built-in circuitry
Built-in demagnetization detection
Built-in OverTemperature Protection (OTP)
Short-Winding Protection (SWP) and OverCurrent Protection (OCP)
Internal VCC generation allowing start-up from rectified mains voltage
Natural dimming curve by logarithmic correction, optimized for human eye response,down to 1 %
The SSL2103 is suitable for various power requirements including:
LED modules such as LED spots and down-lights
LED strings suitable for retail displays etc.
