230 V 7 W GU10 buck converter SSL2101 reference board

1. Introduction

This document describes the application and operation of a 230 V 7 W dimmable LED driver featuring SSL2101. The reference board has a GU10 LED lamp compatible form factor. The buck converter topology provides a simple and efficient solution for mains dimmable LED recessed light applications not requiring galvanic isolation.

Remark: Unless otherwise stated, all voltages are in V. The total input power (VA) to the board is 230 V/41 mA = 9.4 W. The board is design ed to

drive a 5-LED load, delivering an output power of 6.5 W at 415 mA and 15.6 V (DC). The Power Factor (PF) is 0.9 which give an actual input power of 0.9  9.4 W = 8.5 W. The resulting efficiency is 76 %. The Total Harmonic Distortion (THD) is 30 %. The board complies with EMI and safety regulations.

Audible noise requirements of < 25 dBA are realized across the complete dimming range of currently available dimmers in the market.

The board dimensions are shown in Figure 1

. The board is designed with the components

allowing enough headroom when the board is inserted into a GU10 lamp base. The assembled top and bottom board views are shown in Figure 2

and Figure 3.

WARNING Lethal voltage and fire ignition hazard

The non-insulated high voltages that are present when operating this product, constitute a risk of electric shock, personal injury, death and/or ignition of fire.

This product is intended for evaluation purposes only. It shall be operated in a designated test area by personnel qualified according to local requirements and labor laws to work with non-insulated mains voltages and high-voltage circuits. This product shall never be operated unattended.

4. Functional description

4.1 General

The 230 V, 7 W buck reference board uses the SSL2101 con trol IC to drive a load of up to 5-LEDs. The SSL2101 is a Switched Mode Power Supply (SMPS) controller with an integrated MOSFET. Detailed information about the SSL2 101 operation is contained in the SSL2101 SMPS IC for dimmable LED lighting data sheet.

The converter operates in Discontinuous Conduction Mode (DCM) or Boundary Conduction Mode (BCM). In BCM, valley switching detection is used to minimize magnetic component and switching losses while enhancing efficiency . A valley-fill circuit is added to obtain high-power factor.

The reference board is triac dimmable and can be used in combination with most leading and trailing edge dimmers. During dimming, the rectified mains voltage is averaged and attenuated and supplied to both BRIGHTNESS and PWMLIMIT pins of the SSL2101. As a consequence, the converter duty cycle or frequency is reduced and as a result the LED output current.

Dimming compatibility is defined as smooth dimming without any flashing artifacts across the complete dimming range. This reference board provides a dimming compatibility of > 85 % when tested with a current selection of 30 trailing and leading-edge dimmers.

5. Reference board connections

The GU10 LED driver board takes a 230 V, 50 Hz mains supply and supports a 5-LED load.

Remark: Make all connections with the input power is switched off.

• Connect the 5-LED load as output load together with power meter at both inputs and

outputs.

• Connect V

(230 V/50 Hz) using an isolating transformer to the input connection

points of the buck converter. Alternatively use an AC power supply with limited output current capability (for example; 200 mA).

• Increase V

to 230 V and measure the different parameters as shown in Table 2.

• When testing dimmer compatibility, connect a leading or trailing edge dimmer

between V

and the buck converter input connection points.

Remark: Use protective a shield over application and never touch the board when measuring or testing.
