Overview
The AP6508FE-13 is a synchronous step-down DC/DC buck converter manufactured by Diodes Incorporated. It integrates high-side and low-side N-channel power MOSFETs to deliver up to 3A of output current. The device operates with an input voltage range of 4.5V to 21V and supports a fixed switching frequency of 500kHz. Key electrical parameters include a maximum quiescent current of 70µA, a feedback reference voltage of 0.8V, and thermal shutdown protection. The component is housed in a lead-free SOIC-10 package.
Feature Summary
- Integrates high-side and low-side N-channel power MOSFETs for efficient synchronous rectification
- Fixed 500kHz switching frequency enables the use of small external passive components
- Includes comprehensive protection features such as thermal shutdown and soft-start capability
Applications
- Point-of-load regulation for industrial equipment
- Power supply stages for consumer electronics
- Battery-powered portable devices requiring efficient voltage conversion
Procurement Notes
Verify the suffix '-13' confirms the reel quantity specification when ordering. Ensure the operating environment remains within the specified temperature range to maintain performance integrity. Cross-reference the datasheet revision date to confirm compatibility with current design requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring a compact solution with integrated power switches. The fixed 500kHz frequency balances efficiency and component size. Verify that the input voltage does not exceed the 21V absolute maximum rating. Consider the thermal dissipation capabilities of the SOIC-10 package for the expected load conditions.
Part Context
This part belongs to the AP65xx series of synchronous buck converters from Diodes Incorporated. These ICs are designed to provide high-efficiency voltage regulation in space-constrained applications. The series typically offers various current ratings and packaging options to suit different power delivery needs across multiple industries.
Replacement Considerations
Direct replacements must match the 3A current rating, 21V input limit, and 500kHz frequency. Check pinout compatibility for the SOIC-10 package. Evaluate thermal performance and control loop stability when substituting with other synchronous buck regulators.
