EVLHVLED007W35F STMicroelectronics

EVLHVLED007W35F 35W LED driver with very low THD, based on HVLED007 transition mode flyback controller Data brief (THD) in flyback converter operating in Transition mode (Quasi-Resonant). Fast startup and protections with auto-restart are available for safe operation in lighting environments. Features AC input voltage from 90 V to 265 V (frequency range 45 - 66 Hz) Isolated DC bus voltage (Flyback topology): 48 V / 730 mA max. High Power Factor Flyback with very low THD: 100 AC: PF>0.99, THD<3% full load 230 AC: PF>0.98, THD<5% full load Efficiency: >89 % full load Mains harmonics: meets EN61000-3-2 and JEITA-MITI Class-C EMI: according to EN55022 Class-B RoHS compliant Description The EVLHVLED007W35F supplies a stable and isolated 48 V voltage bus suitable for secondary side circuitry (e.g., LED current generators) for a total output power of 35 W when a wide range of input voltages is applied at its input. An auxiliary 12 V output is also present to supply small circuits which absorb a maximum current of 15 mA. Thanks to an STMicroelectronics patented control embedded on HVLED007, the main feature of this design is the very low input current distortion January 2019 DB3810 Rev 1 1/8 For further information contact your local STMicroelectronics sales office. www.st.com5 1 & 1 5 1 Vout = 48V 5 5 5 5 & = +6 1 1 1 & & & 5 X 1 - & 5 5 B 5 5 5 1 1 *B 4 & & 5 5 5 = & & & & 5 1 5 1 S Q = 5 %, 6 5 & 1B 5 5 = 1 < 1B 5 & & & & 5 5 59 8 =& 9& =& +6 1 5 1 1 5 5 &2 & 1 &2 5 &7 &6 )9 ) &7 &6 & 5 +9 & & & 5 = & 5 5 5 5 5 1 5 5 1 9& 5 5 1 / ,6 5 5 & 5 1 = & & 1 - 5 HFQQ DF 5 5 & & 1 8 1 5 5 1 a tel r n a vti e to T 1 a tel r n a vti e to B R 1 a lte r n a vti e to T 2 B SI 1 9& 9= 1 B 5 1 alet r natvi e to D 1 1B 1 1B 1B 1 1 1 S 5 1 1 S 1 V Evaluation board schematic EVLHVLED007W35F 1 Evaluation board schematic Figure 1.
