AS1103 - AMSCO

AS1103 (AS1101 - AS1104) Low-Dropout LED Drivers

The AS110x family are LED drivers providing matched current source bias for any color LED, including white and blue. LED current is programmable using an external resistor. The AS1101 LED currents are typical 460 x ISET (per LED) at an LED cathode voltage of 150mV and typical 650 x ISET at an LED cathode voltage of 1V. The AS1102, AS1103, and AS1104 LED curr.
