TS19721DCS RLG Taiwan Semiconductor

TS19721D Taiwan Semiconductor Single-Stage PFC Buck Current Control LED Driver With High Voltage MOSFET Integrated DESCRIPTION FEATURES TS19721D a very efficient constant current controller Integrated 600V Power MOSFET for driving LED lamps in non-dimmable lighting Low THD <20% (Option) applications. The IC provides a high power factor Constant current accuracy within 2.5% correction and constant current accuracy with High Power Factor Correction >0.9 boundary conduction mode (BCM) operation in a Boundary Current Mode control single stage buck topology. The TS19721D controller LED open protection & short protection is easy to integrate with a small BOM and includes an Over current protection (OCP) internal high voltage power MOSFET for PWM control. Over temperature protection (OTP) Compliant to RoHS directive 2011/65/EU and in Total harmonic distortion (THD) and efficiency are accordance to WEEE 2002/96/EC. optimized by an external resistor. The line and load Halogen-free according to IEC 61249-2-21 regulation of LED current are easily maintained to definition. within 2.5%. TS19721D also provides V over- CC voltage protection, and output open/short circuit APPLICATION protection. LED lighting system SOP-8 Pin Definition: 1. CS 2. COM 3. N/C 4. Drain 5. RT 6. GND 7.
