Overview
The AP62150WU-7 is a synchronous step-down DC/DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2V to 18V and delivers up to 1.5A of output current. The device features a fixed switching frequency of 1.3MHz and supports adjustable output voltages from 0.8V to the maximum input limit. Packaged in a compact SOT-563 surface-mount housing, it is designed for high efficiency and thermal performance in space-constrained applications.
Feature Summary
- Synchronous buck topology for enhanced conversion efficiency
- Integrated high-side and low-side power switches
- Fixed internal switching frequency reduces external component count
- Adjustable output voltage via external resistor divider
Applications
- Point-of-load regulation for embedded systems
- Power supply stages for industrial control equipment
- Voltage conversion for portable battery-operated devices
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm pinout and electrical characteristics. Ensure the ordering part number matches the required package variant. Cross-reference datasheet revisions to validate compliance with current environmental standards before finalizing procurement specifications.
Selection Notes
Select this component when an input voltage up to 18V and continuous output current of 1.5A are required. The 1.3MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the load profile remains within the thermal limits defined by the SOT-563 package dimensions and ambient operating conditions.
Part Context
This part belongs to the AP62150 series of synchronous buck converters from Diodes Incorporated. The series targets applications requiring efficient voltage translation from higher bus voltages to lower logic or peripheral levels. The WU suffix typically denotes the specific tape-and-reel packaging configuration for automated assembly.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Generic replacements may differ in pin compatibility or thermal resistance.
