AP3019AKTTR-G1

LED Driver IC Overview

The AP3019AKTTR-G1 is a single-channel LED backlight driver IC manufactured by Diodes Incorporated. It utilizes a boost topology with an internal Schottky diode and operates within an input voltage range of 2.5 V to 16 V. The device provides an adjustable output voltage up to 38 V and supports a maximum switch current of 550 mA. It functions at a fixed switching frequency of 1.2 MHz and includes PWM dimming capabilities for brightness control. The component is housed in a TSOT-23-6 package and is rated for operation between -40°C and +85°C.

LED Driver IC Feature Summary

• Integrates an internal Schottky diode to minimize external component count
• Supports PWM dimming for precise LED brightness regulation
• Features adjustable output voltage capability for flexible LED string configurations

LED Driver IC Applications

• LED backlight drivers for portable electronic displays
• General-purpose step-up DC-DC conversion for low-power systems

LED Driver IC Procurement Notes

Verify the specific suffix 'KTTR' against official Diodes Incorporated documentation to confirm the TSOT-23-6 package variant, as distributor listings may conflate it with the SOT-23-6 'KTR' version. Confirm end-of-life status through authorized channels prior to design finalization. Ensure moisture sensitivity level handling protocols are followed during assembly due to the component's classification.

LED Driver IC Selection Notes

Select this component when a compact boost converter with integrated rectification is required for LED applications. The 1.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 550 mA output current meets the target LED array requirements and that the 16 V maximum input voltage aligns with the system power supply constraints.

LED Driver IC Part Context

This part belongs to the AP3019A series of LED lighting drivers from Diodes Incorporated. The series focuses on efficient backlighting solutions for mobile devices. The AP3019AKTTR-G1 specifically denotes the tape-and-reel packaging format within the TSOT-23-6 footprint family, distinguishing it from cut-tape or other package variants like the standard SOT-23-6.
