LMR33620CRNXT

Voltage Regulators - DC DC Switching Regulators Overview

The LMR33620CRNXT 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 features a fixed switching frequency of 2.1 MHz, enabling the use of small external components. It supports adjustable output voltages from 1 V to 24 V and includes integrated soft-start and shutdown functions. The component is housed in a compact 12-pin VQFN-HR package and is rated for operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Ensure compatibility with required thermal management solutions given the VQFN-HR package. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference ordering information with manufacturer documentation to avoid substitution errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range and moderate output current are required. The 2.1 MHz frequency is suitable for applications prioritizing board space over extreme light-load efficiency. Consider thermal performance requirements based on the expected load and ambient conditions. Verify that the output voltage range meets the target application specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR33620 series of synchronous buck converters. It shares architectural similarities with other members like the LMR33620BRNX but differs in specific electrical parameters such as switching frequency or EMI filtering capabilities. The CRNX variant specifically denotes the standard commercial grade version within this product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR33620CRNXR is the reel-packaged equivalent of this cut-tape component. For automotive applications, consider the LMR33620CQ5RNXTQ1 which holds AEC-Q100 qualification. Always verify pin-to-pin compatibility and electrical specifications before substituting.
