AP64500QSP-13

Overview

The AP64500QSP-13 is a high-voltage synchronous buck converter manufactured by Diodes Incorporated. It operates with an input voltage range of 3.8V to 40V and delivers a maximum output current of 5A. The device features an adjustable output voltage starting from 0.8V, integrated into an SO-8EP package. It utilizes a fixed switching frequency of 570kHz and includes comprehensive protection mechanisms such as over-current, over-temperature, and short-circuit protection.

Feature Summary

Synchronous rectification architecture for enhanced conversion efficiency
Integrated compensation network minimizing external component count
Built-in thermal shutdown and over-current protection circuits

Applications

Point-of-load regulation in industrial equipment
Power supply stages for automotive infotainment systems
Voltage regulation for edge computing nodes

Procurement Notes

Verify the specific suffix 'QSP' against the manufacturer's official datasheet to confirm qualification status and pinout compatibility. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by Diodes Incorporated. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement.

Selection Notes

Select this component when a 40V input tolerance and 5A continuous load capability are required within a compact SO-8EP footprint. The fixed 570kHz frequency supports efficient passive component selection. Consider the thermal performance characteristics of the exposed pad package for high-density board layouts requiring robust heat dissipation.

Part Context

This part belongs to the AP64500 series of high-voltage synchronous buck converters from Diodes Incorporated. The series is designed for applications demanding high efficiency and small form factors. The QSP variant typically denotes automotive-grade qualification, distinguishing it from standard commercial versions within the same functional family.
