The TS19310 has built-in functions of phase dimmable, and included protection function related VCC over-voltage protection, open-LED protection, short-LED protection, overtemperature protection, primary side current limit, and gate clamp is within. The TS19310 is the sense switch current from CS voltage multiplier by test data input signal (TDIS) to get the output current information by system close loop feedback. The average output current can express by below formula. IOUT NP 0.333* NS 2 RS Where: ● IOUT is the average output current ● NP is the primary-side turn ratio ● NS is the secondary-side turn ratio ● 0.333 is the reference potential setting of IC ● 2 is the reference potential setting of IC ● η is the efficiency ● RS is the sensing resistor connected between the MOSFET source and the GND Pin Detail Pin 1: Compensation This is the output of the gm amplifier. Connect with a suitable RC network to ground. Pin 2: Ground GND is the reference node of internal circuit. 5/8 Version: A14 TS19310A/B Single-Stage PFC TRIAC Dimmable LED Driver Pin 3: Current Sense MOSFET current signal sensing for multiply, phase angle decode and current limit setting function. 1.25 ICS(Limit) RS Where: ICS is the input current sense IC internal CS Pin 1.25V Over voltage level RS is the sensing resistor connected between the MOSFET source and GND Pin 4: Output Gate drive for external MOSFET switch and has built-in gate clamp function. TS 1 No 93 t R 10B eco CX mm 6 en de d Pin 5: VCC Power supply for the controller during normal operation. The controller will start up when VCC reaches 18V (typical) and will shut-down when VCC voltage is below 9.5V (typical). A decoupling capacitor should be connected between the VCC and GND pin as close as possible. The TS19310 performs VCC over voltage protection though VCC pin. Once VCC pin exceeds 32V, TS19310 turns off and latches the MOSFET until VCC goes below VCC_OFF. Pin 6: DMG The Output voltage is reflected by the auxiliary winding (NA) voltage of Flyback transformer, the DMG pin can sense output information to depart from start up voltage (VO_STR) and protection voltage (VO_OVP). When DMG sense voltage under VO_STR, the circuit will work on short circuit protection, f STR=1/tSTR. When DMG sense voltage over VO_OVP, the circuit will work on over voltage protection, it will latch out off until VCC goes below VCC_OFF.
