Overview
The AOZ1036PI is a high-efficiency, easy-to-use 5A synchronous buck regulator from Alpha & Omega Semiconductor. It operates within an input voltage range of 4.5V to 18V and provides up to 5A of continuous output current with an adjustable output voltage down to 0.8V. The device features internal soft start, fixed 500kHz PWM operation, cycle-by-cycle current limit, pre-bias start-up, short-circuit protection, and thermal shutdown. It is available in thermally enhanced 5x4 DFN-8 and exposed pad SO-8 packages, rated for ambient temperatures from -40°C to +85°C.
Feature Summary
- Synchronous buck architecture with integrated high-side and low-side switches
- Fixed 500kHz PWM switching frequency for compact external component sizing
- Comprehensive protection suite including thermal shutdown and cycle-by-cycle current limit
Applications
- Point of load DC/DC converters
- LCD TV power supplies
- Set top boxes
- DVD / Blu-ray players/recorders
- Cable modems
- PCIe graphics cards
Procurement Notes
Verify the specific suffix 'PI' against the manufacturer's official datasheet to confirm package type (SO-8) and temperature rating. Ensure compatibility with required input/output voltage ranges and thermal management solutions for the target application environment.
Selection Notes
Select this component for applications requiring a robust 5A synchronous buck solution with integrated protections. Consider the SO-8 package for ease of assembly if thermal dissipation requirements are met by the PCB layout. Verify that the 500kHz switching frequency aligns with EMI constraints and inductor size preferences.
Part Context
The AOZ1036 series belongs to Alpha & Omega Semiconductor's EZBuck family of synchronous buck regulators. These devices are designed for high efficiency and ease of implementation in portable and consumer electronics. The PI suffix typically denotes the SO-8 package variant, distinguishing it from other package options like the DFN-8.
Replacement Considerations
Check for direct pin-compatible alternatives within the same EZBuck family or similar 5A synchronous buck regulators from other manufacturers. Ensure input voltage range, output current capability, and package dimensions match the existing design constraints.
