5 / 16 page ![]() LV5028TT No.A1999-5/16 Pin Functions Pin No. Pin name Pin function Equivalent circuit 1 ACS ACS pin senses AC Voltage. If this function isn’t used, please connect GND. VIN ACS GND 2 REF_OUT Built-in 3V Regulate out Pin. If this function isn’t used, please connect to nothing. VIN VREF-OUT (3V typ) GND 3 REF_IN External LED current Limit Setting pin. If less than VREF (0.61V) voltage is input, Peak current value is used at the input voltage. If more than REF_IN voltage is input, it is done at VREF voltage. If this function isn’t used, please connect nothing. VIN REF_IN CS GND 4 CS LED current sensing in. If this terminal voltage exceeds VREF (Or REF_IN), external FET is OFF. And if the voltage of the terminal exceeds 1.9V, LV5028TT turns to latch-off mod VIN REF_IN CS GND 5 GND GND pin. VIN OUT GND 6 OUT Driving the external FET Gate Pin. 7 VIN Power supply pin. Operation : VIN > UVLOON Stop: VIN < UVLOOFF Switching Stop : VIN > VINOVP 8 OUT2 This pin drive the FET which is stabilized the TRIAC dimming application. If ACS is less than 3V, OUT2 turn High voltage. If this function isn’t used, please connect nothing. 1k Ω VIN OUT2 GND |
