SSL2109 series GreenChip controller for LED lighting Rev. 3 — 4 June 2012 Product data sheet 1. General description The SSL2109 series is a range of high-voltage Integrated Circuits (IC) for driving LED lamps in general lighting applications. The main benefits of this IC include: • • • • Small Printed-Circuit Board (PCB) footprint, and compact solution High efficiency (up to 95 %) Ease of integration and many protection features Low electronic Bill Of Material (BOM) The IC is supplementary to the SSL2108 series but without an internal switch. The IC range has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the dV/dt supply is used with capacitive coupling from the drain, or any other auxiliary supply. This functionality provides full flexibility in the application design. An internal clamp limits the supply voltage. The IC provides accurate output current control to within 5 % LED current accuracy. The IC can be operated using Pulse-Width Modulation (PWM) dimming and has many protection features including easy LED temperature feedback. www.DataSheet.net/ 2. Features and benefits  LED controller IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply  Part of a high-efficiency switch mode buck driver product family  Controller that has power-efficient boundary conduction mode of operation with:  No reverse recovery losses in freewheel diode  Zero Current Switching (ZCS) for switch turn-on  Zero voltage or valley switching for switch turn-off  Minimal required inductance value and size  Direct PWM dimming possible  Fast transient response through cycle-by-cycle current control:  Negligible AC mains ripple in LED current and minimal total capacitor value  No over or undershoots in the LED current  No binning on the LED forward voltage required  Internal Protections:  UnderVoltage LockOut (UVLO) Datasheet pdf - http://www.DataSheet4U.co.kr/ NXP Semiconductors SSL2109 series GreenChip controller for LED lighting  Leading-Edge Blanking (LEB)  OverCurrent Protection (OCP)  Short-Winding Protection (SWP); SSL2109T only  Internal OverTemperature Protection (OTP)  Brownout protection  Output Short Protection (OSP)  Low component count (see Figure 4) LED driver solution:  No dim switch and high-side driver required for PWM dimming  Easy external temperature protection with a single NTC  Option for soft-start function  Compatible with wall switches with built-in indication light during standby  IC lifetime easily matches or surpasses LED lamp lifetime 3. Applications The SSL2109 series is intended for compact LED lamps with accurate fixed current output for single mains input voltages. Mains input voltages include 100 V, 120 V and 230 V (AC). The output signal can be modulated using a PWM signal. The power range is determined by external components. 4. Quick reference data Table 1. Symbol VCC ICC(INT) VHV VDRAIN fconv Quick refe.
