3 1. Introduction The SSL21101T demo board uses a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified mains. It is designed to drive LED devices. The device includes a high-voltage power switch and a circuit enabling start-up directly from the rectified mains voltage. It has accurate control of the output current. 2. Features Isolated AC/DC offline non-dimmable LED driver from 190 V (AC) to 230 V (AC) Primary side sensing (no optocoupler required) True current source behavior: LED current independent of mains voltage, LED voltage, temperature and coil variation High LED current accuracy ( 3 % typical) Efficiency 80 % to 87 % depending on the flyback application Smart Digital Control (SDC) to deal with two kinds of applications: High Power Factor (> 0.95) and low Total Harmonic Distortion (THD) (< 30 %) Low form factor (low LED current ripple with small electrolytic capacitors), compatible with exception clause IEC Protections: Short-Winding Protection (SWP) Internal OverTemperature Protection (OTP) LED short protection LED open protection UnderVoltage LockOut (UVLO) External Negative Temperature Coefficient (NTC) overtemperature detection for LED current regulation Internal supply voltage generation enabling start-up from the rectified mains voltage S014 package User manual Rev August of 31

27 8. Demo board functional description 8.1 Component selection Mode The mode is set by selecting the right Mode voltage value according to the data sheet (see Table 9) and tuning the R5 and R13 values Pin RMAIN Pin RMAIN is used to detect the zero crossing of the mains voltage. The value of resistor R main is selected to get 300 A running on pin RMAIN. The optimum values of resistor R main are given in the Table 14. Table 14. LTHD mode: R main optimization results V main (V) R main ATHD (%) M [1] k 23 full main 710 k <26 [1] For 230 V LTHD applications, R main is chosen at 740 K to provide a starting point at 85 V mains R SOURCE and I ILEDREF R SOURCE and I ILEDREF are key values to keep V SOURCE within the right range. Both contribute in the LED current control Input capacitor In LR mode, the input capacitor value must be high enough to stay in Discontinuous Conduction Mode (DCM). This means that the rectified main voltage must be high enough to avoid a long switch turn-on time ( t1 SW ). In LTHD mode, a minimum value is required for stability. However, this value must not be so high that it retains a high Power Factor capability Output capacitor Capacitor C6 helps stabilizing the output voltage and the LED current. In LR mode, the low capacitor value is used to filter the current at the 50 khz/100 khz switching frequency. In LTHD mode, a higher capacitor value is required to filter the current at 100 Hz EMI filter A -filter (C/L/C) is installed on the V main access to be in line with European standard EN55015A Inrush resistor On all boards, an inrush resistor (R9) limits the maximum peak current on the mains to 2 A when switching on the application. This resistor increases the losses at low mains voltage. User manual Rev August of 31

28 The losses in the inrush resistor are higher in an LR application than in an LTHD application. In an LR application, an active damping circuitry can be used to obtain better efficiency. The RC system connected to rectified main voltage controls a Triac, which can be used to bypass the inrush resistor Transformer A transformer is required for the following reasons: To convert the rectified mains voltage to a lower voltage for the output LED string. To supply the SSL21101T chip using the auxiliary windings. To isolate the output LED voltage from the main voltage The primary winding is calculated to keep the application in DCM for both LR and LTHD modes. 9. Printed-Circuit Board (PCB) The SSL21101T demo board is a low-cost 2-layer PCB. The board size is approximately 900 mm 2. The size of the ground around the IC is optimized to obtain the required thermal resistance. The heating is reduced using several vias joining the ground on both PCB sides.
