LMR33620BRNXR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR33620BRNXR 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 protection features. The component is housed in a compact 12-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 moisture sensitivity levels during assembly. Confirm that the ordering part number matches the required switching frequency variant within the LMR33620 series.

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 allows for smaller inductors compared to lower-frequency alternatives. Consider the thermal performance of the VQFN-HR package for high-duty cycle applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR33620 series of non-isolated DC-DC converters. It shares architectural similarities with other members like the LMR33630 but differs in maximum output current ratings. The series is designed for space-constrained designs requiring high efficiency and minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR33620CRNXR: Different switching frequency (2.1 MHz vs 2.1 MHz, verify exact BR vs CR specs). LMR33620ARNXT: Lower switching frequency (400 kHz). LMR33630BRNXR: Higher current rating (3 A).
