Overview
The AOZ1036PI is a high-efficiency, easy-to-use 5A synchronous buck regulator from Alpha & Omega Semiconductors. It operates within an input voltage range of 4.5V to 18V and provides up to 5A of continuous output current, adjustable 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 low on-resistance switches
- Integrated protection mechanisms including thermal shutdown and current limit
- Adjustable output voltage capability starting from 0.8V
- Fixed frequency PWM operation for consistent performance
Applications
- Point of load DC/DC converters
- LCD TV power supplies
- Set top boxes
- DVD / Blu-ray players/recorders
- Cable modems
Procurement Notes
Verify the package type matches the required PCB footprint, specifically distinguishing between the 5x4 DFN-8 and exposed pad SO-8 variants. Confirm that the supplier provides genuine Alpha & Omega Semiconductors products to ensure reliability and adherence to specified electrical characteristics. Check for any specific handling requirements associated with the thermally enhanced packages during assembly.
Selection Notes
Select this component when a compact, high-efficiency solution is needed for converting higher input voltages (up to 18V) to lower regulated outputs around 0.8V or higher. It is suitable for applications requiring up to 5A continuous current with built-in protections. Consider the thermal performance of the chosen package relative to the expected ambient temperature and load conditions.
Part Context
The AOZ1036PI belongs to the EZBuck family of synchronous buck regulators designed by Alpha & Omega Semiconductors. This series focuses on providing high efficiency and ease of implementation for various consumer and industrial electronic devices. The PI suffix typically denotes the specific package configuration, which is critical for board layout and thermal management considerations.
Replacement Considerations
Check for other members of the AOZ1036 family, such as AOZ1036DI, which may offer different package options but identical electrical specifications. Ensure any substitute maintains the same input voltage range, current rating, and pinout compatibility if direct replacement is required.
