Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM53601AQDSXRRB

LM53601AQDSXRRB

Voltage Regulators - DC DC Switching Regulators Overview

The LM53601AQDSXRRB is an automotive-grade synchronous step-down DC-DC converter from Texas Instruments. It features a wide input voltage range of 3.8V to 36V and delivers up to 1A output current. The device operates at a fixed switching frequency of 2.1MHz, enabling the use of small external components. It provides an adjustable positive output voltage with a minimum setting of 3.3V and a maximum of 6V. Packaged in a compact 10-WSON (3x3) surface-mount case, it supports junction temperatures from -40°C to 150°C and holds AEC-Q100 qualification for automotive reliability.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'RRB' against official Texas Instruments documentation to confirm exact reel specifications and tape-and-reel dimensions. Ensure compatibility with automated assembly processes by checking moisture sensitivity level (MSL) ratings and recommended reflow profiles. Confirm that the component meets RoHS3 compliance requirements for your target market regulations before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing automotive circuits requiring a robust 1A buck converter with a 36V input tolerance. The 2.1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the thermal design accommodates the 10-WSON package constraints under maximum load conditions. Verify that the required output voltage range falls within the 3.3V to 6V adjustability limits specified in the datasheet.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM53601-Q1 family of automotive synchronous step-down converters. It shares core architecture with variants like LM53600-Q1 but offers higher current capacity. The 'AQ' designation indicates automotive grade qualification, while 'DSX' denotes the specific WSON package type. Related parts include LM53601MQUDSXRQ1 and LM53601NQDSXRRB, which may differ in temperature ranges or packaging options.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM53601AQDSXTQ1, which shares identical electrical characteristics and pinout. Verify that any alternative maintains the same 10-WSON package dimensions and thermal pad configuration to ensure mechanical compatibility on existing PCB layouts.
