RP402K001D-TR

Voltage Regulators - DC DC Switching Regulators Overview

The RP402K001D-TR is a boost DC/DC converter from the Nisshinbo RP402K series, designed for step-up voltage regulation. It operates with an input voltage range of 600 mV to 4.6 V and provides an adjustable output voltage between 1.8 V and 5.5 V. The device delivers a maximum output current of 800 mA at a fixed switching frequency of 1 MHz. It functions within a temperature range of -40°C to +85°C and utilizes a DFN-2020-8 package for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the RP402K family. Confirm package type DFN-2020-8 matches design requirements. Check RoHS compliance status via manufacturer documentation before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an 800 mA boost converter is required with a low minimum input voltage of 600 mV. The 1 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the application does not require a shutdown feature, as this variant lacks one.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the RP402K series of switching regulators manufactured by Nisshinbo Micro Devices. The series focuses on high-efficiency step-up converters suitable for mobile and industrial applications requiring reliable power management from single-cell lithium batteries or similar low-voltage sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

RP402K002B-TR offers similar boost functionality but differs in output current (800 mA) and input voltage range (600 mV to 4.6 V). Verify pin compatibility and thermal performance before substitution.
