AS1103 - (AS1101 - AS1104) Low-Dropout LED Drivers

Download the AS1103 datasheet PDF. This datasheet also covers the AS1101 variant, as both devices belong to the same (as1101 - as1104) low-dropout led drivers family and are provided as variant models within a single manufacturer datasheet.

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.

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 connected to the CTRL pin. The AS110x family can drive up to 4 high-current LEDs.
