LMR36520FADDAR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR36520FADDAR is a synchronous step-down DC-DC converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 4.2 V to 65 V and delivers up to 2 A of output current. The device features adjustable output voltage from 1 V to 28 V, a fixed switching frequency of 400 kHz, and low quiescent current of 26 uA. It is housed in an 8-PowerSOIC package with a thermal pad and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix ADDAR corresponds to the 8-PowerSOIC package with tape-and-reel packaging. Confirm RoHS compliance status as specified in the latest datasheet revision. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity level classification. Cross-reference pinouts with official TI documentation to prevent layout errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard 36 V limits but require compact synchronous buck topology. The 2 A current rating suits moderate power applications where size constraints favor integrated solutions. Evaluate thermal performance requirements given the SOIC package's heat dissipation characteristics under continuous load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LMR36520 series designed for high-voltage applications. Shares architectural similarities with LMR36510 but offers higher output current capacity.
