LMR23630DRRT

Voltage Regulators - DC DC Switching Regulators Overview

The LMR23630DRRT is a synchronous step-down converter from Texas Instruments' SIMPLE SWITCHER family, housed in a WSON-12 package. It supports an input voltage range of 4 V to 36 V and delivers up to 3 A of output current. The adjustable output voltage spans from 1 V to 28 V. Key electrical parameters include a fixed switching frequency of 400 kHz and a quiescent current of 75 uA. The device operates within a temperature range of -40°C to +125°C and features integrated shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRRT corresponds to the WSON-12 package and reel/cut-tape packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required pinout and thermal pad specifications for your PCB layout. Cross-reference with the latest datasheet revision to confirm any design-in updates or lifecycle status changes before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 36 V input range and 3 A continuous current are required in a compact form factor. The fixed 400 kHz frequency simplifies filter design compared to adjustable frequency variants. Consider the WSON-12 thermal performance for your specific ambient conditions. Compare against the LMR23615 if lower current (1.5 A) or adjustable frequency options are sufficient for the application requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR23630 series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LMR23615 but offers higher current capability. The series is designed for applications requiring robust performance and minimal external components. The DRRT suffix indicates the specific tape-and-reel packaging variant available for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes within the same family include the LMR23630ADDAG4, which offers the same electrical specifications but utilizes a different ADDA package type. Verify pin-to-pin compatibility and thermal characteristics when transitioning between package styles. No alternative cross-brand replacements are confirmed in public documentation.
