AP4460AEN

Overview

The AP4460AEN is a synchronous boost switching regulator IC manufactured by Asahi Kasei Microdevices. It features an adjustable output voltage range from 2.5V to 4V with a single positive output configuration. The device operates within an input voltage range of 0.14V to 4V, supporting low-voltage start-up capabilities. It is housed in a 24-WFQFN package with an exposed pad, measuring 4x4 mm, designed for surface-mount installation. The component supports operation across a temperature range of -30°C to 85°C.

Feature Summary

Synchronous rectification topology for improved efficiency
Adjustable output voltage control via external feedback
Ultra-low minimum input voltage capability for energy harvesting
Compact surface-mount packaging with thermal dissipation pad

Applications

Portable electronic devices requiring efficient step-up conversion
Battery-powered systems with low initial charge levels
Energy harvesting circuits utilizing low-voltage sources
Mobile communication equipment power management

Procurement Notes

Verify component authenticity through authorized distributors as the AP4460AEN is officially obsolete and no longer manufactured. Confirm that replacement parts meet equivalent electrical specifications and pin compatibility. Check datasheet revisions for any design-in changes. Ensure supply chain documentation aligns with end-of-life procurement policies. Validate substitute components against original performance requirements before integration.

Selection Notes

Consider the AP4460AEN for applications requiring wide input voltage ranges starting near zero volts. Evaluate the need for synchronous rectification to maximize efficiency in space-constrained designs. Assess thermal performance requirements given the small QFN footprint. Compare against active alternatives if long-term availability is critical for production cycles.

Part Context

The AP4460AEN belongs to the AP4460 series of DC-DC converters produced by Asahi Kasei Microdevices. This series focuses on high-efficiency power management solutions for portable electronics. The specific AEN suffix denotes the package type and tape/reel configuration. The component represents AKM's approach to low-voltage boost regulation technology.
