Introduction 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 SSL2101 task light board is a 120 V (AC), dimmable, 450 mA LED driver board. It employs a flyback converter to drive power LEDs that require galvanic isolation. The board is designed to highlight high performance dimming, wide dimmer compatibility, high efficiency and the capability of driving various numbers of LEDs. 019aac594 Fig 1. SSL2101 task light board 2. 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 2. UM10477 User manual b.

Set-up procedures The board input voltage is 120 V (AC) and it can drive either a 5-LED or 9-LED string at 450 mA. The output voltage range is from 15 V to a maximum of 30 V. The LED load is connected to the output terminals as shown in Figure 3. Do not connect LED load to the driver board when the driver board is powered to avoid damage caused to LEDs due to the hot-plugging inrush current. 120 V (AC) 60 Hz task light board A + dimmer + V L A + V T1 - N = 005 A LED LED board 019aac582 Fig 3.

Functional description The SSL2101 IC is used to configure a flyback converter operating at 60 kHz and produces a constant output current (450 mA) to drive up to 9-LEDs. The current corresponds to an output voltage between 15 V and 30 V. When an input voltage is applied to the SSL2101, it is initially powered by the rectified voltage. Once the SSL2101 starts switching, the SSL2101 is then supplied by the inductor’s auxiliary winding to improve efficiency. The flyback converter operates in Discontinuous Conduction Mode (DCM) to minimize the magnetic component and switching losses. In addition, a high Power Factor (PF) is obtained due to the DCM operation. When operating in Boundary Conduction Mode (BCM) at full load, flyback converter efficiency is optimized and enhanced by the valley switching detection. When mains dimmers are used, the circuit detects the rectified voltage change. In addition, the circuit reduces the duty cycle and switching frequency to reduce the output current for deep dimming. To increase the dimmer compatibility without sacrificing efficiency, the board uses a highly efficient, bleeding circuit to ensure flicker-free deep dimming with a wide range of mains dimmers. It detects circuit current and if necessary, supplements bleeding current to meet the required hold currents of triac dimmers. The bleeding circuit ensures the widest dimmer compatibility while keeping heat generation to the minimum. The 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 ensure compliance with the EMI requirement of EN55015/FCC15. Five LEDs were used in the test application for optimal performance of this reference design. The design can be adapted to meet other LED solutions.
