产品描述
The SGM3136 is a 3-channel ultra low dropout constant source parallel LED driver. The SGM3136 uses an internal resistor to set the bias current for three LEDs, which are matched to ±3%.
The SGM3136 incorporates a single wire interface to program the output current at 16 continuous steps. It has an internal deglitch circuit for filtering the noise of the EN input.
The SGM3136 requires only a 35mV dropout voltage at a 20mA load. The feature makes SGM3136 ideal for battery-operated systems, such as personal digital assistants.
The SGM3136 is available in Green SOT-23-6 package and is specified over an ambient temperature range of -40°C to + 85°C .
