RP604K331A-TR

Voltage Regulators - DC DC Switching Regulators Overview

The RP604K331A-TR is a fixed-output Buck-Boost DC/DC converter manufactured by Nisshinbo Micro Devices. It provides a stable 3.3 V output with a maximum current capacity of 300 mA. The device operates within an input voltage range of 1.8 V to 5.5 V, supporting both step-down and step-up conversion topologies. Key electrical specifications include an ultra-low quiescent current of 0.3 uA and a typical operating supply current of 10 nA. It is housed in a compact 12-UFDFN package with exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm the fixed 3.3 V output configuration. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status through the provided environmental documentation before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required from a variable input source between 1.8 V and 5.5 V. The ultra-low quiescent current makes it suitable for energy-constrained designs. Consider the DFN-2730-12 package dimensions for PCB layout constraints compared to other PMIC options in the portfolio.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the RP604K series of switching regulators designed for high efficiency under light loads. It complements other Nisshinbo power management ICs like the RP506K buck converters and RP173K LDOs, offering a specialized solution for applications needing bidirectional voltage conversion capabilities rather than simple step-down regulation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The RP604K501A-TR serves as a direct functional substitute within the same series, differing only in its fixed 5 V output specification while maintaining identical topology and package.
