Analog Devices ADP5501 Datasheet
The ADP5501 from Analog Devices is a single‑chip boost converter designed to drive up to six white LEDs for display backlights. It features programmable LED current, three auxiliary LED sinks, and an integrated ambient light sensor that can automatically adjust brightness to extend battery life. Communication with a host processor is handled via an I²C‑compatible serial interface and an interrupt line.
The device operates over a 2.7 V to 5.5 V supply range and includes protection features such as over‑voltage, thermal shutdown, and current‑limit. Detailed specifications, pin functions, register maps, and typical performance curves are provided for designers of media‑enabled handheld and portable devices.
