AP3030KTTR-E1

LED Driver IC Overview

The AP3030KTTR-E1 is a regulated LED driver IC manufactured by Diodes Incorporated, designed for high-efficiency boost topology applications. It features an internal switch capable of handling 1.4A switching current and operates with a fixed 1MHz switching frequency to minimize external component size. The device supports analog dimming control for precise brightness regulation and accepts input supply voltages ranging from 2.7V to 16V. Packaged in a compact TSOT-23-6 surface-mount case, it ensures reliable performance across an operating temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a high-current internal power switch for efficient step-up voltage conversion
• Provides analog dimming capability for smooth and linear brightness adjustment
• Operates at a fixed 1MHz frequency to reduce passive component footprint

LED Driver IC Applications

• LED backlighting systems
• Portable electronic device illumination
• General-purpose LED driving circuits

LED Driver IC Procurement Notes

Verify the specific suffix E1 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics, as suffixes often denote package or tape-and-reel variations. Confirm RoHS compliance status directly with the supplier documentation. Check for any Product Change Notifications (PCN) or End-of-Life (EOL) notices issued by Diodes Incorporated prior to finalizing procurement plans.

LED Driver IC Selection Notes

Select this component when designing boost converters for LED strings requiring analog dimming control within a 2.7V to 16V input range. Ensure the application demands a switching current capacity up to 1.4A and fits within the thermal constraints of the TSOT-23-6 package. Validate that the required operating temperature range aligns with the specified -40°C to +85°C ambient limits.

LED Driver IC Part Context

This part belongs to the AP3030 series of LED drivers from Diodes Incorporated, specialized for portable applications. It complements other PMIC solutions by offering a dedicated, compact regulator for lighting needs. The TSOT-23-6 packaging allows for space-constrained designs common in mobile devices and consumer electronics where board real estate is limited.
