Introduction 1.1 Scope of this document 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. The demo board (see Figure 1 and Figure 2) is a 120 V, 21 W, dimmable LED driver featuring the SSL2103. The board employs a flyback converter to provide a simple and efficient solution for mains dimmable, LED recessed-light applications that require galvanic isolation. The demo board is designed to highlight high performance dimming, wide dimmer compatibility, cost-effectiveness and high efficiency in dimmable LED driving applications. The demo boards efficient bleeding circuit ensures wide dimmer compatibility and flicker-free dimming operation for leading edge (triac) and falling edge (transistor) dimmers. The board operates at around 70 kHz and produces a constant output current up to 700 mA to drive 8 to 9 LEDs. The corresponding output voltage range is 23 V to 30 V. The optimized circuit design, external MOSFET and valley switching help to achieve efficiency up to 85 %. Figure 1 and Figure 2 show populated views of the demo board. 019aac377 Fig 1.

Safety warning Connect the board to the mains voltage. Avoid touching the board while it is connected to the mains voltage at all times. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a variable transformer is always recommended. 019aab174 019aab173 a. Isolated Fig 3. b. Not isolated Variable transformer isolation symbols 3.

Functional description The SSL2103 driver IC is used to configure a flyback converter to generate a regulated output current for driving LEDs. When an input voltage is applied, the SSL2103 is initially powered up from the rectified voltage. When the SSL2103 starts switching, the SSL2103 is then supplied by the auxiliary winding for increased efficiency. See Figure 10.

All rights reserved. 4 of 17 UM10475 NXP Semiconductors 120 V 21 W 700 mA reference design using SSL2103 The flyback converter operates in Discontinuous Conduction Mode (DCM) to minimize magnetic component and switching losses. High-Power Factor (PF) is obtained automatically due to DCM operation. With an operation in Boundary Conduction Mode (BCM) at full load, is efficient, optimized and enhanced by valley switching detection. An external MOSFET is used to allow high-power applications. When mains dimmers are used, the circuit detects the rectified voltage change and reduces the duty cycle and switching frequency. This action reduces the output current for deep dimming. The demo board adopts a more efficient bleeding circuit. This results in flicker-free deep dimming with a wide range of mains dimmers to increase the dimmer compatibility without sacrificing efficiency. It detects circuit current and if necessary, supplements bleeding current enough for the required hold currents of triac dimmers. The bleeding circuit ensures the widest dimmer compatibility while keeping the minimum heat generation. The reference circuit also includes an active damper to increase the efficiency and limit the inrush current during the phase cutting transient. An ElectroMagnetic Interference (EMI) filter is included to comply with the conducted EMI requirement of EN55015/FCC15. Remark: Nine LEDs were used in the test application for optimal performance of the reference design. The design is adaptable to match other LED solutions. 5. Dimmer compatibility Several dimmers with different specifications have been tested as the dimming performance of the board varies. Table 2 shows the range of mains dimmers tested for compatibility with the SSL2103 demo board. Table 2.

Quick setup procedure The demo board is supplied by 120 V (AC) and drives 8 to 9 LEDs up to 700 mA. The output voltage range of the demo board is between 23 V to 30 V. The output current can be adjusted down to 450 mA with potentiometer (R20) at the output. The LED load is connected to the terminals W3 and W4. The output voltage is limited to 35 V. Connect an LED load to the driver board before powering up the board. This action avoids any potential damage to LEDs due to the inrush current from hot-plugging.
