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. To protect the
external power MOSFET from being damaged by supply over voltage, the TS19702 Output pin voltage is
clamped to about 15V.
