TS19702

High Power Factor Corrector LED Driver

1/9

Version: A12

SOT-26

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.
