NXP SSL2101

Description

The SSL2101 is a Switched Mode Power Supply (SMPS) driver 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 high-voltage power switch, a circuit to allow start-up directly from the rectified mains voltage and a high-voltage circuitry to supply the phase cut dimmer.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 external bleeder transistors to provide extended dimmer interoperability

Features

• 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 VCC generation allowing start-up from the rectified mains voltage
• Natural dimming curve by logarithmic correction, down to 1 %
• Limited external components required because of the high integration level
• Thermal enhanced SO16 wide body package
• Suitable for flyback and buck applications.

Typical applications

• LED strings suitable for retail displays, etc.
• Retro-fit lamps (for example, GU10, E27)
• SSL applications below 15 W
• LED modules such as LED spots, down-lights
