Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix HA0 against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS and Reach compliance requirements for your region. Cross-reference the part number with the latest datasheet revision to validate pin assignments and electrical characteristics before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a compact 3A step-down solution within a 4.5V to 16V input window. The fixed 1.1MHz frequency allows for smaller external passive components compared to lower frequency alternatives. Consider the 8-pin HLSOP package constraints for PCB layout. Evaluate the need for battery backup functionality, which is specific to the RAA23012x variant, not this model.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the RAA23012x/RAA23013x family of 16V input, 3A step-down DC/DC converters. The family differentiates primarily by package options, with the RAA23013x utilizing an 8-pin HLSOP format. These devices are designed for general-purpose power management in space-constrained environments requiring reliable synchronous buck conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same family include the RAA23012x series, which shares identical electrical specifications but offers a 16-pin HTSSOP package option. Verify that any replacement maintains the 3A output current capability and 1.1MHz switching frequency to ensure circuit stability.
