1 / 7 page  TS19721D Taiwan Semiconductor Document Number: DS_P0000278 1 Version: A15 Single-Stage PFC Buck Current Control LED Driver With High Voltage MOSFET Integrated DESCRIPTION TS19721D a very efficient constant current controller for driving LED lamps in non-dimmable lighting applications. The IC provides a high power factor correction and constant current accuracy with boundary conduction mode (BCM) operation in a single stage buck topology. The TS19721D controller is easy to integrate with a small BOM and includes an internal high voltage power MOSFET for PWM control. Total harmonic distortion (THD) and efficiency are optimized by an external resistor. The line and load regulation of LED current are easily maintained to within ±2.5%. TS19721D also provides VCC over- voltage protection, and output open/short circuit protection. FEATURES ● Integrated 600V Power MOSFET ● Low THD <20% (Option) ● Constant current accuracy within ±2.5% ● High Power Factor Correction >0.9 ● Boundary Current Mode control ● LED open protection & short protection ● Over current protection (OCP) ● Over temperature protection (OTP) ● Compliant to RoHS directive 2011/65/EU and in accordance to WEEE 2002/96/EC. ● Halogen-free according to IEC 61249-2-21 definition. APPLICATION ● LED lighting system SOP-8 Pin Definition: 1. CS 2. COM 3. N/C 4. Drain 5. RT 6. GND 7. VCC 8. CS Notes: Moisture sensitivity level: level 3. Per J-STD-020 ABSOLUTE MAXIMUM RATINGS (T A = 25°C unless otherwise specified) (Note 1) PARAMETER SYMBOL LIMIT UNIT Power Supply Pin VCC 40 V RT Voltage to GND VRT -0.3 to 5.5 V DRAIN Voltage to GND VOUT -0.3 to 620 V CS Voltage to GND VCS -0.3 to 5.5 V COM Voltage to GND VCOM -0.3 to 5.5 V Junction Temperature Range TJ -40 to +150 °C Storage Temperature Range TSTG -65 to +150 °C Lead Temperature (Soldering 10 sec) TLEAD 260 °C Power Dissipation @ TA=25 °C PD 0.3 W ESD Rating (Human Body Mode) (Note 2) HBM 2 kV ESD Rating (Machine Mode) (Note 2) MM 200 V |
