Overview
The AP62250WU-7-N is a high-voltage synchronous buck DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2 V to 18 V and delivers up to 2.5 A output current. The device features a fixed switching frequency of 1.3 MHz and supports adjustable output voltages from 0.8 V to 7 V. It includes integrated shutdown functionality and operates within a temperature range of -40°C to +125°C. The component is housed in a compact TSOT-26 package.
Feature Summary
- Synchronous buck topology for efficient power conversion
- Integrated shutdown control for power management
- Wide input voltage capability for flexible design
- High operating junction temperature rating
Applications
- Industrial equipment power distribution
- Automotive electronics systems
- Portable battery-powered devices
- Embedded system voltage regulation
Procurement Notes
Verify the specific suffix against official documentation, as the provided data references AP62250WU-7-N. Confirm RoHS compliance status through manufacturer datasheets. Ensure the TSOT-26 package dimensions match PCB layout requirements. Validate thermal performance specifications for the intended operating environment before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring high input voltage tolerance up to 18 V. The 1.3 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the load current does not exceed 2.5 A. Consider the thermal dissipation capabilities of the TSOT-26 package for high-load applications.
Part Context
This part belongs to the AP62250 series of high-voltage synchronous buck converters from Diodes Incorporated. It shares architectural similarities with other members like the AP62200 but offers higher output current capacity. The series targets applications needing robust voltage regulation under varying input conditions.
Replacement Considerations
The AP62250Z6-7 serves as a functional alternative with identical electrical specifications but utilizes a SOT-563 package instead of TSOT-26. Verify pinout compatibility and thermal characteristics before substitution.
