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 the output voltage 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 housed in a thermally enhanced 5x4 DFN-8 package and is rated for an ambient temperature range of -40°C to +85°C.
Feature Summary
- Synchronous buck architecture with integrated high-side and low-side switches
- Fixed 500kHz switching frequency for compact external component sizing
- Comprehensive protection mechanisms including thermal shutdown and short-circuit protection
- Adjustable output voltage starting from 0.8V
Applications
- Point of load DC/DC converters
- LCD TV power supplies
- Set top boxes
- DVD and Blu-ray players/recorders
- PCIe graphics cards
Procurement Notes
Verify the specific suffix 'PI' corresponds to the 5x4 DFN-8 package variant when sourcing. Confirm that the manufacturer designation matches Alpha & Omega Semiconductors to ensure compatibility with the EZBuck family specifications. Check for any updated revision codes or tape-and-reel specifications if ordering in bulk quantities.
Selection Notes
Select this component for applications requiring a compact, high-efficiency step-down solution with an input voltage up to 18V. The 5A continuous current capability suits moderate power loads. Consider the 500kHz frequency for balancing efficiency and passive component size. Ensure the thermal performance of the DFN-8 package meets the system's heat dissipation requirements under maximum load conditions.
Part Context
The AOZ1036 belongs to the EZBuck family of synchronous buck regulators designed for simplicity and high performance. This series targets portable electronics and consumer appliances where space and efficiency are critical. The PI suffix typically denotes the specific package type and pin configuration within the broader AOZ1036 product line.
