Overview
The AP65500SP-13 is a synchronous step-down DC/DC converter IC manufactured by Diodes Incorporated. It features an adjustable output voltage range from 0.8V to 16V with a maximum continuous output current of 5A. The device operates at a fixed switching frequency of 340kHz and supports an input voltage range suitable for various power rails. It is housed in an 8-SOIC package with an exposed pad for thermal management and functions within an operating temperature range of -40°C to 85°C.
Feature Summary
- Synchronous rectification architecture for enhanced conversion efficiency
- Integrated control loop simplifies external component requirements
- Exposed pad package design facilitates effective heat dissipation
Applications
- Point-of-load regulation for embedded systems
- Power supply stages in industrial equipment
- Voltage conversion for communication infrastructure
Procurement Notes
Verify the specific suffix 'SP-13' against official Diodes Incorporated documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with standard surface-mount assembly processes for SOIC packages. Cross-reference the manufacturer's latest datasheet revision to validate pinout assignments and electrical characteristics prior to final procurement decisions.
Selection Notes
Select this component when a 5A output capacity is required with a fixed 340kHz switching frequency. The adjustable output range up to 16V provides flexibility for various load requirements. Consider the thermal performance of the 8-SOIC package with exposed pad for adequate heat sinking in enclosed environments compared to smaller footprint alternatives.
Part Context
This part belongs to the AP655xx series of synchronous buck converters from Diodes Incorporated, designed for high-current applications. The series typically includes variants with different switching frequencies and current ratings, such as the AP65502 or AP65503, allowing designers to choose based on size and efficiency constraints while maintaining similar control architectures.
Replacement Considerations
Direct replacements include other Diodes Incorporated parts like the AP65502SP-13 or AP65503SP-13, which share similar form factors but differ in switching frequency or light-load efficiency optimizations. Verify pin-to-pin compatibility and thermal requirements before substitution.
