FAN5701UMP30X-ON

Overview

The FAN5701UMP30X-ON is a six-output LED driver IC from onsemi, utilizing a switched capacitor charge pump topology. It operates within a supply voltage range of 2.7 V to 5.5 V and features an internal switching frequency of 1.2 MHz. The device provides a configurable output current capability of up to 180 mA per channel, with a standard regulation setting of 30 mA. It supports both I2C digital control and PWM dimming for precise brightness adjustment. Packaged in a compact 16-UMLP (3x3) surface-mount format, it is designed for applications requiring efficient multi-string LED driving.

Feature Summary

• Integrates a six-channel charge pump DC-DC regulator for driving multiple LED strings from a single low-voltage source.
• Supports dual dimming methods including high-frequency PWM and digital I2C interface for system integration.
• Configurable output current allows adaptation to various LED forward voltage requirements without external sensing resistors.

Applications

• Backlighting for mobile handsets and media tablets
• LED illumination in wireless LAN cards and broadband access devices
• Portable multimedia players and MP3/MP4 devices

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix and marking against the official datasheet to ensure correct package and temperature grade. Check for end-of-life status or obsolescence notices prior to final design approval. Ensure RoHS compliance documentation matches the manufacturing date code.

Selection Notes

Select this component when a low-profile solution is required for driving six LEDs from a single-cell lithium battery or USB power source. Consider the 16-UMLP package constraints for PCB layout thermal management. Evaluate the 1.2 MHz switching frequency against EMI requirements for sensitive RF circuits in portable electronics.
