LMR33620CDDAR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR33620CDDAR is a synchronous step-down voltage converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 3.8 V to 36 V and delivers up to 2 A of output current. The device supports adjustable output voltages between 1 V and 24 V. Key electrical parameters include a typical quiescent current of 25 uA, a fixed switching frequency of 2.1 MHz, and an operating temperature range from -40°C to +125°C. It utilizes a SO-PowerPAD-8 package for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CDDAR' against official datasheets to confirm the SO-PowerPAD-8 package and reel packaging configuration. Ensure compatibility with required thermal management solutions given the compact footprint. Confirm humidity sensitivity handling procedures during assembly. Validate that the 2.1 MHz switching frequency aligns with electromagnetic interference constraints in the target system design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 36 V is required alongside moderate 2 A output current capabilities. The fixed 2.1 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the SO-PowerPAD-8 package relative to the QFN-HR variants if board space or thermal dissipation requirements differ significantly from standard designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR33620 series of wide-input-voltage synchronous buck converters. It shares core specifications with other package variants such as the LMR33620ARNXT, which offers a different form factor but similar electrical characteristics. The series is designed to simplify power supply designs for industrial applications requiring robust performance across varying load conditions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR33620CDDA is available in tube packaging instead of reel format. LMR33620ARNXT provides the same electrical performance in a VQFN-HR-12 package.
