Overview
The AOZ1915DI is a positive adjustable boost switching regulator IC manufactured by Alpha & Omega Semiconductor Inc. It operates with an input voltage range of 2.7V to 5.5V and provides a single output adjustable up to 22V. The device supports a switch current of 1.5A and offers selectable switching frequencies of 600kHz or 1.2MHz. It is housed in a compact 12-pin VFDFN package measuring 4mm x 3mm with an exposed pad, designed for space-constrained applications.
Feature Summary
- Adjustable output voltage capability up to 22V
- Selectable switching frequency options at 600kHz or 1.2MHz
- Compact 4mm x 3mm 12-pin VFDFN package design
Applications
- Battery-powered portable devices
- Cellular phones and handheld electronics
- Low-voltage power supply systems
Procurement Notes
Verify the specific suffix and marking code against official Alpha & Omega Semiconductor documentation to confirm the exact switching frequency configuration and pinout compatibility. Ensure the sourcing channel provides genuine components with traceable manufacturing dates to avoid counterfeit risks associated with small-outline packages.
Selection Notes
Select this component when a compact footprint is required for boosting low input voltages (2.7V–5.5V) to higher levels (up to 22V). Consider the 1.5A switch current limit and available switching frequencies (600kHz/1.2MHz) relative to external inductor size and efficiency requirements for the target application.
Part Context
This part belongs to the AOZ1915 series of boost converters from Alpha & Omega Semiconductor. It is designed for high-efficiency power management in mobile and portable electronics where board space is limited. The device integrates necessary control logic for step-up conversion within a thermally enhanced DFN package.
Replacement Considerations
Check for direct substitutes within the AOZ1915 family or other Alpha & Omega boost regulators with compatible 2.7V–5.5V input ranges and similar 12-pin DFN footprints. Verify that alternative parts support the required 22V output and 1.5A current capacity.
