AP6502S-13

Overview

The AP6502S-13 is a synchronous step-down switching regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 4.75V to 23V and provides an adjustable output voltage from 0.925V to 16V. The device delivers a continuous output current of 2A at a fixed switching frequency of 240kHz. Packaged in an 8-SOIC (3.90mm wide) with exposed pad, it supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated synchronous rectification for improved efficiency
• Fixed 240kHz switching frequency reduces external component size
• Built-in protection mechanisms including overcurrent and thermal shutdown

Applications

• Point-of-load regulation for embedded systems
• Industrial control power supplies
• Consumer electronics DC-DC conversion

Procurement Notes

Verify the specific suffix 'S' against official Diodes Incorporated documentation to confirm package variant and tape/reel specifications. Confirm availability status as distribution channels may list obsolete or discontinued inventory. Ensure the selected distributor provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component when a compact 8-pin SOIC solution is required for 2A buck applications. The fixed 240kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the load requirements do not exceed the 2A limit and that the input voltage remains within the specified 4.75V to 23V window.

Part Context

This part belongs to the AP6502 series of synchronous buck converters from Diodes Incorporated. It is designed for high-efficiency power conversion in space-constrained environments. The series typically features integrated MOSFETs and control logic to minimize external bill of materials.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic replacements must match the 2A current rating, 240kHz frequency, and 8-SOIC package dimensions.
