Overview
The AP61102QZ6-7 is a low-voltage synchronous buck DC-DC converter manufactured by Diodes Incorporated. It operates within an input voltage range of 2.3 V to 5.5 V and delivers a maximum output current of 1 A. The device utilizes a SOT-563 package and supports adjustable output voltages from 600 mV to 5.5 V. Designed for high efficiency, it integrates internal compensation and protection features including overcurrent, overtemperature, and undervoltage lockout.
Feature Summary
- Integrates synchronous rectification for improved power conversion efficiency in compact designs.
- Features constant on-time control architecture to manage wide input-to-output voltage ratios effectively.
- Includes comprehensive protection mechanisms such as thermal shutdown and short-circuit protection.
Applications
- Portable consumer electronics requiring efficient step-down regulation
- Battery-powered devices with limited input voltage headroom
- Embedded systems utilizing single-cell lithium-ion power sources
Procurement Notes
Verify the specific suffix designation to ensure compatibility with required automotive or industrial qualification standards. Confirm that the SOT-563 package dimensions align with the target PCB footprint constraints. Review the official datasheet for thermal dissipation requirements under maximum load conditions to validate heatsinking needs.
Selection Notes
Select this component when a 1 A output capability is sufficient for the application's power budget. Ensure the input supply remains within the 2.3 V to 5.5 V operational window. Consider the SOT-563 package size if space optimization is critical compared to larger regulator footprints.
Part Context
This part belongs to the AP61xxx series of low-voltage buck converters from Diodes Incorporated. It shares architectural similarities with other members like the AP61062QZ6-7 but differs in output current ratings. The series targets applications demanding high efficiency in small form factors.
Replacement Considerations
Direct substitutes include the AP61062QZ6-7 for lower current requirements. Verify pinout compatibility and electrical specifications before swapping with other manufacturers' synchronous buck regulators.
