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.
SSL2103主要特性和優勢:
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 %
SSL2103應用:
The SSL2103 is suitable for various power requirements including:
Retro-fit lamps
LED modules such as LED spots and down-lights
LED strings suitable for retail displays etc.

SSL2103 230 V 12 W E27裝飾燈LED驅動器演示板
SSL2103 230 V 12 W E27 retrofit LED driver demo board
This SSL2103 user manual is intended for 230 V applications of 12 W demo boards of E27-type (and similar type) retrofit light sources.
The circuit implements a Boundary Conduction Mode (BCM) buck converter. It is mains dimmable for both forward phase (triac) dimmers, and reverse phase (transistor) dimmers. It is designed for demonstrating high performance and high efficiency. It produces a 400 mA regulated output current to drive 10 LEDs at a 230 V (AC) input. With the help of an external MOSFET, an efficiency of up to 85 % can be achieved.
This demo board is connected to a high AC voltage (up to 265 V). Avoid touching the demo board during operation. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a fixed or variable transformer (Variac) is always recommended.
