Overview
The AP6502ASP-13 is a synchronous step-down DC-DC converter 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 maximum output current of 2A with a typical switching frequency of 240kHz. It utilizes current-mode control architecture for stable performance. The component is housed in an 8-pin SOIC package with an exposed pad, designed for surface-mount installation. It supports a maximum duty cycle of 90% and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates synchronous rectification for improved efficiency
- Employs current-mode control for rapid transient response
- Supports wide input voltage ranges for versatile power applications
Applications
- Point-of-load regulation for embedded systems
- Power supply stages for industrial equipment
- Battery-powered device voltage conversion
Procurement Notes
Verify the specific suffix 'ASP-13' against official Diodes Incorporated documentation to confirm pinout and thermal characteristics. Confirm end-of-life status as distributor listings indicate discontinuation. Ensure compatibility with existing PCB footprints for the 8-SOIC package with exposed pad before procurement.
Selection Notes
Select this component when a 2A synchronous buck solution is required within a 23V input limit. The adjustable output allows flexibility for various logic levels. Consider the 240kHz frequency for balancing component size and efficiency. Verify that the 8-SOIC package fits the mechanical constraints of the target design.
Part Context
This part belongs to the AP65xx series of synchronous buck converters from Diodes Incorporated. It shares architectural similarities with other members like the AP65353 but differs in current rating and specific electrical parameters. The series targets general-purpose power management needs in compact form factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Diodes Incorporated application engineering for direct replacements or functional equivalents if this discontinued part is required.
