FAN5341UMPX

Overview

The FAN5341UMPX is a single-channel asynchronous boost LED driver IC from the FAN5341 series, manufactured by onsemi. It operates with an input voltage range of 2.7 V to 5.5 V and supports switching frequencies up to 1.2 MHz. The device delivers a maximum output voltage of 22 V and provides an output current capability of 25 mA. Designed for compact applications, it utilizes a UMLP-6 package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Asynchronous boost topology for efficient step-up conversion
• Integrated high-frequency switching controller
• Compact six-lead ultra-miniature leadless package

Applications

• Portable electronic device backlighting
• LED indicator circuits in mobile devices
• Battery-powered lighting modules

Procurement Notes

Verify the specific suffix 'UM' corresponds to the UMLP-6 package configuration required for your design. Confirm that the 25 mA output current meets the load requirements. Ensure the operating environment stays within the specified -40 °C to +85 °C range. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a small form factor is critical due to its UMLP-6 footprint. Choose this part for low-power LED applications requiring up to 25 mA drive current. Consider the 1.2 MHz switching frequency for minimizing external passive component size. Verify input voltage compatibility with the 2.7 V minimum requirement.

Part Context
