NEW PRODUCT ANNOUNCEMENT www.taiwansemi.com TS19721DCS Single-Stage PFC Buck Current Control LED Driver with Integrated High Voltage MOSFET Pin Definition: 1. CS 5. RT 2. COM 6. GND 3. N/C 7. VCC 4. Drain 8. CS SOP-8 The TS19721D is a very efficient constant current controller for driving LED lamps in nondimmable lighting applications. The IC provides a high power factor correction capability 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%. The TS19721D also provides VCC over-voltage protection, and system output open/short circuit protection to increase IC performance.
