Overview
The AP62301WU-7 is a high-voltage synchronous buck DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2V to 18V and delivers a maximum output current of 3A. The device features a fixed switching frequency of 750kHz and supports adjustable output voltages from 0.8V to 7V. Packaged in a compact TSOT-26 (SOT-23-6 Thin) surface-mount housing, it is designed for efficient power management in space-constrained applications.
Feature Summary
- Integrated synchronous rectification for improved efficiency
- High-voltage input capability up to 18V
- Compact TSOT-26 package for space-saving designs
Applications
- Portable electronic devices requiring efficient step-down conversion
- Battery-powered systems with wide input voltage ranges
- General-purpose power management in consumer electronics
Procurement Notes
Verify the specific suffix 'WU' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure compatibility with the required output voltage range and load current specifications before integration. Confirm RoHS compliance status through the latest product documentation.
Selection Notes
Select this component when a 3A output current and 18V maximum input voltage are required in a small footprint. Compare against the AP62300 series if lower current or different packaging is preferred. Verify that the 750kHz switching frequency aligns with EMI constraints and inductor selection requirements.
Part Context
This part belongs to the AP6230x family of high-voltage buck converters from Diodes Incorporated. It shares architectural similarities with the AP62300 and AP62301Z6 variants but differs in package type. The TSOT-26 package distinguishes it from larger SOT-563 alternatives while maintaining similar electrical performance profiles.
Replacement Considerations
The AP62300WU-7 is a related variant within the same family. Cross-reference pinouts and thermal pads carefully. No direct drop-in substitutes are confirmed in public documentation without verifying package-specific mechanical dimensions.
