LMR23630FDRRT

Voltage Regulators - DC DC Switching Regulators Overview

The LMR23630FDRRT is a SIMPLE SWITCHER synchronous step-down converter from Texas Instruments, housed in a WSON-12 package. It supports an input voltage range of 4 V to 36 V and delivers up to 3 A output current with adjustable output voltages from 1 V to 28 V. The device operates at a fixed switching frequency of 400 kHz and features a typical quiescent current of 75 uA. It functions within a temperature range of -40°C to +125°C and includes integrated protection features such as thermal shutdown and current limit.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'FDRRT' against the official Texas Instruments datasheet to confirm the exact reel quantity and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit products. Confirm that the WSON-12 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 36 V input range and 3 A continuous output are required in a compact form factor. The fixed 400 kHz frequency balances efficiency and component size effectively. Consider the 75 uA quiescent current for battery life optimization. Ensure the application environment stays within the specified -40°C to +125°C operating temperature range for reliable performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR23630 family of SIMPLE SWITCHER converters, designed for general-purpose DC/DC applications. It shares architectural similarities with other devices in the series but is distinguished by its 3 A current capability and 36 V maximum input rating. The FDRRT suffix indicates a specific packaging configuration for surface-mount assembly.
