LMR23625CFDDAR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR23625CFDDAR is a SIMPLE SWITCHER® synchronous step-down DC-DC converter from Texas Instruments. It integrates a high-side N-channel MOSFET and delivers up to 2.5A of continuous output current. The device operates with an input voltage range of 4V to 36V, supporting non-regulated sources common in industrial applications. It features a fixed switching frequency of 2.1MHz and offers selectable Forced PWM or PFM modes for optimized efficiency across load conditions. The unit includes internal loop compensation, reducing external component count.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated synchronous rectification with peak current mode control
• Selectable forced PWM or PFM operation for light-load optimization
• Internal loop compensation simplifies design and minimizes components
• Precision enable input supports system power sequencing

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load regulation
• Battery-powered systems requiring low quiescent current
• Non-regulated power supply conversion
• Embedded controller power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'C' indicates automotive qualification grade and 'DDAR' specifies the HSOIC PowerPAD package with tape-and-reel packaging. Confirm RoHS compliance status matches project requirements. Ensure the supplier provides valid traceability documentation for the specific manufacturing lot. Cross-reference the datasheet revision to ensure feature compatibility with existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a 36V input range and 2.5A output are required in a compact form factor. The integrated MOSFETs reduce solution size compared to discrete solutions. Choose between Fixed Frequency PWM for noise-sensitive loads or PFM for higher light-load efficiency. Verify thermal performance in the target enclosure, as the SO-PowerPAD package relies on PCB copper for heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR23625 family of SIMPLE SWITCHER converters. It shares pinout compatibility with the LMR23610 (1A) and LMR23630 (3A) variants, allowing for flexible PCB layout scaling within the same product line. The series is designed for ease of use with minimal external components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-to-pin replacements include the LMR23610 for lower current needs and the LMR23630 for higher current demands. Non-integrated equivalents require significant circuit redesign. Verify that any substitute maintains the 2.1MHz switching frequency if EMI filtering is already implemented.
