产品描述 |
The SGM3135 driver provides a simple solution for a matched current source for common Anode LED configuration. The SGM3135 can drive three LEDs or one LED at three times the current. The factory preset current value is 20mA per channel. The SGM3135 requires only a 40mV dropout voltage at a 20mA load on each output to match the LED brightness. The SGM3135 is available in Green SOT-23 |
