SD6904STR Datasheet | SILAN MICROELECTRONICS

DESCRIPTION SD690XS is designed for non-isolated LED driving with floating Buck structure and built-in 600V MOSFET. With this structure, inductor current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate. Also, high PF in full range is available as its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency. SD690XS integrates various protections, such as output open circuit protection, output short circuit protection, cycle-by-cycle current limit protection, over temperature protection and VCC over voltage protection. The start-up current and operating current are low and highlight APPLICATION LED can be driven with high efficiency in full range ∗ Bulb Lamp (85VAC~265VAC). ∗ T5/T8 LED Lamp FEATURES ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ Proprietary constant control method (Patent) Built-in 600V MOSFET Constant current with high accuracy for LED (<±3%) PF>0.9 in full voltage range Boundary-Conduction mode LED short circuit protection (Patent) LED open circuit protection VCC over/under voltage protection Over temperature protection Over current protection ∗ Various LED Lighting ORDERING INFORMATION Part No. SD6901STR SD6902STR SD6904STR Package SOP-7-225-1.27 SOP-7-225-1.27 SOP-7-225-1.27 Marking SD6901S SD6902S SD6904S Material Halogen free Halogen free Halogen free Packing Tape&Reel Tape&Reel Tape&Reel HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://.silan..cn REV:0.4 2013.04.07 Page 1 of 7 Silan Microelectronics BLOCK DIAGRAM SD690XS_Datasheet VCC Undervoltage UVLO lockout VCC OVP 50us Debounce + - 22V Internal bias VREF5.5V DRAIN 5/6 ZCD control OTP Logic control S Q R DRV + - 2 Polarity conversion CS reference Gm amplifier + - TON parator ABSOLUTE MAXIMUM RATINGS Characteristics Supply voltage Feedback voltage Sample voltage P voltage DRAIN voltage Junction Range Storage...
