Low-Dropout LED Drivers
1 General Description
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 currents are typical 230 x ISET (per LED) at an LED cathode
voltage of 150mV and typical 325 x ISET at an LED cathode
voltage of 1V where ISET is the current through the external resistor connec...
