FAN5333SX

Overview

The FAN5333ASX is a single-output boost DC-DC converter designed for LED driver applications, manufactured by onsemi. It operates with an input voltage range of 1.8V to 5.5V and delivers a maximum output voltage of 30V. The device features an internal switch capable of handling up to 1.5A. It supports both analog and PWM dimming methods for brightness control. Operating at a fixed frequency of 1.5MHz, the component is housed in a compact SOT-23-5 surface-mount package. It functions within a temperature range of -40°C to 85°C.

Feature Summary

Integrates a high-current internal power switch for efficient boost conversion
Supports dual dimming modes including analog and pulse-width modulation
Utilizes a small footprint SOT-23-5 surface mount package

Applications

LED backlighting systems
Mobile phone displays
Handheld computer screens

Procurement Notes

Verify current availability status as the FAN5333ASX may be subject to end-of-life notices or discontinuation. Confirm that the specific ordering suffix matches the required package and environmental compliance standards. Cross-reference official manufacturer documentation for any recent product change notifications or marking updates before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a compact boost regulator for single-channel LED driving. Ensure the application input voltage falls within the 1.8V to 5.5V range. Verify that the required LED forward voltage does not exceed the 30V output limit. Consider the 1.5A switch current capability against peak load requirements and confirm compatibility with system dimming control signals.

Part Context

This part belongs to the FAN5333 series of LED drivers from onsemi. It shares architectural similarities with related models like the FAN5332ASX and FAN5333BSX, which also target mobile display backlighting. These components typically offer integrated switches and support various dimming interfaces suitable for portable electronic devices.
