FAN5702UC20X

Overview

The FAN5702UC20X is a configurable LED driver IC manufactured by onsemi, designed for mobile handset backlight applications. It features six independent output channels driven by an internal charge pump topology. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a switching frequency of 1.2 MHz. Each channel provides an adjustable output current capability of up to 30 mA. Control is managed via an I2C interface, allowing for precise regulation and PWM dimming. The component is housed in a compact WLCSP-16 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a charge pump DC-DC converter with six individually controllable LED output channels.
• Enables digital configuration and brightness control through standard I2C communication protocols.
• Supports high-frequency PWM dimming for flicker-free display backlighting performance.

Applications

• Mobile handset LCD backlight systems
• Portable electronic device illumination
• Compact LED lighting modules

Procurement Notes

Verify the specific suffix against official documentation, as variations exist within the FAN5702 family. Confirm availability status, as this part number may be discontinued or subject to allocation restrictions. Ensure compatibility with existing PCB footprints and design-in requirements before finalizing procurement plans.

Selection Notes

Select this component when a low-profile solution is required for multi-channel LED driving in space-constrained portable devices. The integrated charge pump eliminates external inductors, simplifying the bill of materials. Verify that the 30 mA per channel limit meets the target LED string requirements and that I2C bus speed matches system constraints.

Part Context

This device belongs to the FAN5702 series of LED drivers from onsemi. The UC20X designation indicates a specific pinout and electrical characteristic variant within the broader product line. Related variants include the UMP30X and UMP20X, which offer different packaging options such as UMLP-16 while maintaining similar functional architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative models within the same manufacturer portfolio only after verifying pin-to-pin compatibility and electrical parameter alignment with original design specifications.
