STEVAL-ILD004V2

S T E VA L - I L D 0 0 4 V 2 Digital wall dimmer for halogen and low-consumption lamps Data brief Description The STEVAL-ILD004V2 evaluation board represents an innovative and low cost power topology for light wall dimmers using two sensitive TS820-600FP SCRs and a single STGF10NC60KD IGBT to dim 100 - 240 V halogen lamps, SELV halogen lamps through magnetic or electronic transformers, and new CFL and LED dimmable lamps. Control of the board is achieved with STM8S103F2 microcontroller. In comparison with STEVAL-ILD004V1, this board introduces a buck SMPS (operated through the VIPer06XS) instead of a linear power Features supply, for compatibility acrtoss all dimmable LED and CFL lamps. Flicker-free operation with paralleled lamps Operation in 2- or 3-wire configuration Leading-edge control Operation at 110 V or 230 V line rms voltage and 50 Hz or 60 Hz line frequency Dimmable power range: 3 W to 600 W for 230 V rms line 3 W to 300 W for 110 V rms line higher power is possible with larger heatsink Power efficiency 600 W - 230 V > 99% Standby loss 230 V < 0.3 W Short-circuit protection at startup Enhanced interface with push-buttons soft- start and soft-stop memory of last setting Compliance with EMC standards: IEC 61000-4-5: criteria A for 2 kV surge IEC 61000-4-4: criteria A for more than 4 kV Filterless compliance with EN55015 for 600 W -230 V halogen lamp RoHS compliant January 2016 DocID028889 Rev 1 1/5 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-ILD004V2 1 Schematic diagram Figure 1: STEVAL-ILD004V2 circuit schematic (1 of 3) 1 +13 .1V +13 .1V +13 .1V 1 +5V GSPG120 1161120SG 2/5 DocID028889 Rev 1 NOTE SW4: Control Section: SCR s and IGBT 1-2: 2-Wire Connection (Standard) 2-3: 3-Wire Connection (For Light Load) D7 STT H1L0 6 3 J3 V-DC 2 IGBT VCE D3 STT H1L0 6 Q4 1 2 1 SW 4 TTPP11 BS 25 0 R19 SHUN T SP DT D8 10 K LINE 1N414 8 J4 RR2255 1010 EE 2 1 D1 Q1 TS82 0 R3 36 K R20 1N540 4 R1 22 K PD4 SHUN T 51 E D14 IGBT Q1 3 BSS 159 N 1N414 8 TP2 R10 R18 10 E R16 1K 22 K QQ33 R4 10 E PD6 RV2 C15 STGF10NC 60 KD Q1 0 R21 51 E JJ1111 D13 VA RISTOR 10n F L1 C14 BS 17 0 1 R27 22 K CC1177 PD3 680p F PA 1 RV1 2.2u H 1n1n FF Q1 2 VA RISTOR 1N414 8 2STR216 0 D12 1N414 8 Q5 CCOONN33 Q1 1 C18 BS 17 0 2STR116 0 22n F C16 R23 4.7n F Q1 4 BSS 159 N 100 E D2 R2 22 K PD5 R22 C13 R24 F1 1N540 4 0.05 E 15n F 100 k FUSE Q2 TS82 0 D4 STT H1L0 6 J11 GND POWER CONNECTOR 1 1 - NEUTRAL TTPP66 2 - LOAD 3 - LINE
