4 / 7 page TS19704 Single-Stage Primary-Side Control with High PFC LED Driver 4/7 Version: C12 Application Information Function Description The TS19704 is a constant current Flyback controller with primary side control and PFC function for LED lighting applications. Which controller is DCM operation with constant on time based regulator design. In other to achieve high power factor and good EMI performance. This control algorithm fix ICS_PK in wide range variation of Line voltage. We can design transformer critically by ICS(Limit) function. The TS19704 are built-in functions of VCC over voltage protection, open LED protection, short LED protection, over temperature protection, and primary side current limit, and gate clamp within. The TS19704 sense switch current from CS voltage Multiplier by TDIS to provide the integral result(VINT). The avarge VINT is finally 2.5V(Vref) by the system close loop feedback. The avarge output current can express as below.

When DMG sense voltage under VO_STR, the circuit will work on short circuit protection, FSTR=1/Tstr, VCS_PK=0.35V, When DMG sense voltage over VO_OVP, the circuit will work on over voltage protection, it will latch out off until VCC under VCC_OFF. 2 2 1 A S O_STR R R R 3 N N V + × × = 2 2 1 OVPS A S O_OVP R R R V N N V + × × = |
