3 / 8 page TS19450 AC/DC WLED Driver with External MOSFET Universal High Brightness 3/8 Version: A10 Block Diagram Pin Description Pin Function Description 1 VIN This pin is the input of 8V~450V linear regulator 2 CS This pin is the current sense pin used to sense the MOSFET current by means of an external sense resistor. When this pin exceeds the low of either the internal 250mV or the voltage at the LD pin, the GATE output goes low 3 GND Ground return for all internal circuitry. This pin must be electrically connected to the ground of the power train. 4 GATE This pin is the output GATE driver for an external N-CH Power MOSFET 5 PWMD This is the PWM dimming input of the IC. When this pin is pulled to GND, the Gate Driver is turned off. When the pin is pulled high, the GATE driver operates normally. 6 VDD This is the power supply pin for all internal circuits. It must be bypassed with a low ESR capacitor to GND (≥0.1µF) 7 LD This pin is the linear dimming input and sets the current sense threshold as long as the voltage at the pin is less than 250mV (typ.) 8 RT This pin sets the oscillator frequency. When a resistor is connected between RT and GND, the IC operates in constant frequency mode. When the resistor is connected between RT and GATE, the IC operates in constant off-time mode. |
