Overview
The AOZ1252PI is a synchronous buck regulator from the EZBuck series by Alpha & Omega Semiconductor. It integrates high-side and low-side power MOSFETs to deliver a regulated output current of 2A. The device operates with an input voltage range of 4.5V to 36V, supporting fixed output voltages of 3.3V or 5V. It features adjustable switching frequencies up to 500kHz and includes comprehensive protection mechanisms such as over-current, thermal shutdown, and soft-start functionality.
Feature Summary
- Integrates synchronous rectification for improved efficiency
- Supports wide input voltage ranges for versatile applications
- Includes built-in protection against over-temperature and over-current conditions
Applications
- Point-of-load regulation in industrial systems
- Power supply stages for consumer electronics
- Battery-powered equipment requiring efficient step-down conversion
Procurement Notes
Verify the specific suffix 'PI' against official datasheets to confirm pinout and package configuration. Ensure compatibility with required output voltage options and switching frequency settings. Confirm RoHS compliance status and moisture sensitivity level prior to integration into manufacturing processes.
Selection Notes
Select this component when a compact, integrated solution for 2A step-down conversion is required. Consider the fixed output voltage availability and operating temperature range. Evaluate the need for external compensation components based on the desired stability and transient response characteristics.
Part Context
This part belongs to the EZBuck family of synchronous buck regulators designed for high efficiency and minimal external component count. It utilizes advanced control techniques to maintain stable output under varying load and line conditions, suitable for space-constrained designs.
Replacement Considerations
Check for direct pin-to-pin compatible alternatives within the same product family that offer similar current ratings and input voltage ranges. Verify functional equivalence regarding protection features and switching frequency capabilities before substitution.
