AP8800AWT-7

Overview

The AP8800AWT-7 is a single-output DC-DC buck converter LED driver IC manufactured by Diodes Incorporated. It operates within an input voltage range of 8V to 28V and provides a switch current of 370mA. The device features a switching frequency of 600kHz and supports both analog and PWM dimming methods. It is housed in a TSOT-25 package and functions across a temperature range of -40°C to 105°C.

Feature Summary

• Integrates internal power switch for reduced external component count
• Supports combined analog and PWM dimming control
• Includes open LED protection circuitry

Applications

• 1-Watt LED lighting systems
• Single-string LED drivers
• Compact LED modules requiring small passive components

Procurement Notes

Verify the specific suffix 'AWT-7' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and check for obsolescence notices, as some listings indicate potential end-of-life status for this series. Ensure the supplier provides valid traceability documentation.

Selection Notes

Select this component for applications requiring a compact solution with high switching frequency to minimize inductor size. It is suitable for designs needing integrated dimming capabilities without additional controller complexity. Verify that the required output current does not exceed the 370mA limit and that the input voltage remains within the specified 8V to 28V window.

Part Context

This part belongs to the AP880X series of step-down DC-DC converters designed to reduce the number and size of external components. The series utilizes high-frequency operation to allow smaller inductors and capacitors. It targets cost-effective LED driver implementations for general illumination.
