ADP5520ACPZ-R7

Overview

The ADP5520ACPZ-R7 is an LED backlight driver IC featuring a boost topology and integrated I/O expander. It operates on a single supply voltage ranging from 2.7 V to 5.5 V, delivering up to 30 mA output current across four channels with a maximum output voltage of 27 V. The device functions at a switching frequency of 400 kHz and supports I2C control for configuration. Packaged in a 24-pin LFCSP, it ensures reliable operation within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a boost converter with four independent open-drain output channels for LED driving
Includes an I/O expander controlled via I2C interface for system management
Supports wide input voltage range suitable for battery-powered applications

Applications

LED backlight drivers for mobile devices
Portable electronics requiring integrated display illumination and GPIO expansion
Battery-operated systems needing efficient power management

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm package marking and datasheet revision match the specific order requirements. Check for moisture sensitivity handling instructions due to LFCSP packaging. Ensure supply chain documentation aligns with RoHS compliance standards. Validate part number suffixes against official manufacturer catalogs before procurement.

Selection Notes

Select this component when designing circuits requiring combined LED backlighting and general-purpose I/O expansion. Consider the 30 mA per channel limit and 27 V boost capability for LED string configurations. Evaluate the 400 kHz switching frequency for EMI constraints and efficiency requirements. Ensure the I2C addressable interface fits the host microcontroller's available bus resources and pin count limitations.

Part Context

This part belongs to the ADP5520 series, designed for portable applications. It combines power management with digital interface capabilities. The LFCSP-24 package offers compact footprint solutions. The series targets markets demanding high integration levels in small form factor designs.
