Overview
The AOZ1235QI-01 is a synchronous step-down regulator from the EZBuck series by Alpha & Omega Semiconductor. It integrates high-side and low-side power MOSFETs with a control circuit to deliver up to 8A of output current. The device operates with an input voltage range of 2.7V to 28V and supports adjustable output voltages starting from 0.8V. Key features include integrated bootstrap diode simulation, UVLO protection, and thermal shutdown. It is housed in a compact QFN package suitable for space-constrained designs.
Feature Summary
- Integrated synchronous buck converter with built-in power MOSFETs
- Supports wide input voltage range from 2.7V to 28V
- Includes protection mechanisms such as UVLO and thermal shutdown
Applications
- Point-of-load regulation for industrial equipment
- Power supplies for consumer electronics
- Embedded systems requiring efficient step-down conversion
Procurement Notes
Verify the exact suffix (e.g., -01) against the manufacturer's latest datasheet to ensure correct pinout and feature set. Confirm RoHS compliance status and packaging options directly with authorized distributors. Check for any recent revisions or obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a compact, high-efficiency solution is needed for inputs up to 28V. Ensure the required output current does not exceed 8A under worst-case thermal conditions. Verify that the desired output voltage falls within the adjustable range supported by the external resistor network.
Part Context
This part belongs to Alpha & Omega Semiconductor's EZBuck family, which focuses on simplified design and high efficiency. These regulators integrate gate drivers and power switches to reduce external component count. The AOZ1235 variant specifically targets applications requiring moderate current levels in a small footprint.
Replacement Considerations
Check for direct pin-to-pin replacements within the same EZBuck series, such as the AOZ1231QI-01 or AOZ1237QI-01, depending on current requirements. Ensure compatibility with existing PCB layout and thermal management strategies when substituting.
