TS19702 High Power Factor Corrector LED Driver SOT-26 Pin Definition: 1. VCC 2. Ground 3. Output 4. Dimming 5. Compensation 6. Current Sense Description The TS19702 is a highly-integrated, low startup current, average current mode, one cycle control PFC and fixed switching frequency PWM controller. These functions enable the LED driver to easily meet the accuracy average LED current and high power factor requirements. The integrated functions also include the LED short protection, open protection, and internal over temperature protection. The COMP pin controls the duty by connected an RC compensation network to ground and forming the closed loop feedback control.
