6 / 8 page TS19310A/B Single-Stage PFC TRIAC Dimmable LED Driver 6/8 Version: A14 Pin 3: Current Sense MOSFET current signal sensing for multiply, phase angle decode and current limit setting function. S CS(Limit) R 1.25 I 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. 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, fSTR=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. Where: ● V DMG_OVP is the output-over-voltage protection point ● V OVPS is the over voltage protection signal ● V O_STR is the start-up timer ● N A is the number of auxiliary-winding turns ● N S is the number of secondary-winding turns OVP Protection (by DMG) DMG2 DGM2 DGM1 OVPS A S DMG_OVP R R R V N N V × × OVP Protection (by VCC) OVPA A S OVP VCC V N N V × _ Short Circuit Protection R R R V N N V DMG2 DMG2 DMG1 STR O A S Short O × × _ _ RDMG2 NA VCC DMG RDMG1 CDMG |
