AP65552SP-13

Overview

The AP65552SP-13 is a synchronous step-down DC/DC converter from Diodes Incorporated, integrating two high-side N-channel MOSFETs and two low-side N-channel MOSFETs. It operates with an input voltage range of 4.5V to 28V and delivers up to 5A output current. The device features adjustable switching frequency from 300kHz to 2.2MHz via an external resistor. Key protections include over-current protection, thermal shutdown, and soft-start functionality. It is housed in a compact 4mm x 4mm QFN-28 package.

Feature Summary

Integrated synchronous rectification with internal high-side and low-side N-channel MOSFETs for improved efficiency.
Adjustable switching frequency allows optimization for size and performance requirements.
Comprehensive protection mechanisms including over-current, thermal shutdown, and undervoltage lockout ensure reliable operation.

Applications

Industrial equipment power supplies
Telecommunications infrastructure
Consumer electronics

Procurement Notes

Verify the exact suffix 'SP-13' matches your reel quantity and tape-and-reel specifications. Confirm pinout compatibility with your PCB layout. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your environmental conditions.

Selection Notes

Select this component when a 5A output current is needed within a 4.5V to 28V input range. Consider the adjustable frequency feature for EMI management. Evaluate the QFN-28 package for space-constrained designs. Compare thermal performance against alternative packages if heat dissipation is critical.

Part Context

This part belongs to Diodes Incorporated's AP655xx series of synchronous buck converters. The series is designed for medium-power applications requiring high efficiency and compact form factors. The 'SP' indicates specific packaging or variant details within the product line.

Replacement Considerations

Check for direct pin-to-pin replacements such as other AP655xx variants with different current ratings or frequencies. Verify electrical parameters like input voltage range and output current capability before substitution.
