AP3602AKTR-G1

LED Driver IC Overview

The AP3602AKTR-G1 is a step-up (boost) DC-DC regulator designed for LED backlight applications, manufactured by Diodes Incorporated. It operates within an input voltage range of up to 5 V and delivers a fixed output voltage of 5 V with a maximum output current of 100 mA. The device features a switching frequency of 1.2 MHz and a low quiescent current of 13 uA. It is housed in a SOT-26-6 package and supports operation temperatures from -40 C to +85 C.

LED Driver IC Feature Summary

• Integrated boost converter topology optimized for LED backlight driving
• Fixed 5 V output regulation capability
• Low quiescent current consumption for power efficiency

LED Driver IC Applications

• LED backlight drivers
• Portable electronic devices requiring step-up regulation

LED Driver IC Procurement Notes

Verify the specific suffix 'G1' against the manufacturer's latest datasheet to confirm RoHS compliance and lead-free status. Ensure the SOT-26-6 package variant matches your PCB footprint requirements. Confirm that the 1.2 MHz switching frequency aligns with your electromagnetic interference constraints and inductor selection.

LED Driver IC Selection Notes

Select this component when a fixed 5 V output is required from a single-cell lithium battery or similar low-voltage source. The 100 mA output limit suits small LED arrays. Consider the 1.2 MHz frequency for smaller passive components compared to lower-frequency alternatives. Verify thermal performance within the specified -40 C to +85 C operating range for your enclosure design.

LED Driver IC Part Context

This part belongs to the AP3602 series of LED driver ICs from Diodes Incorporated. It is distinct from the AP3125 AC/DC converters and AP3407 buck regulators also listed in the provided data. The AP3602 specifically addresses boost conversion needs for lighting applications rather than general-purpose power management or offline conversion.

LED Driver IC Replacement Considerations
