• Adjustable switching frequency for optimization
• Low quiescent current for standby power savings
• Compact surface-mount packaging

Applications

• Point-of-load regulation
• Industrial equipment power supplies
• Telecommunications infrastructure

Procurement Notes

Verify the exact part number suffix against official documentation, as variations may exist. Confirm component availability status with authorized distributors, as lifecycle changes can affect supply. Ensure compliance with relevant environmental directives such as RoHS before integration into final products.

Selection Notes

Select this component when a compact solution is required for moderate current loads up to 6 A. The wide input voltage range suits various bus architectures. Consider the thermal performance of the PQFN package relative to the expected ambient conditions and load profile during design.

Part Context

This part belongs to the TinyBuck family of integrated synchronous regulators from onsemi. These devices combine power switches and controllers in a small footprint to simplify power supply design. The series targets applications requiring efficient DC-DC conversion in space-constrained environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that offer similar current ratings and input voltage ranges. Verify that any substitute maintains the required switching frequency range and thermal characteristics.
