SNVU621D May 2019 – July 2021 LM61440 , LM61440-Q1 , LM61460 , LM61460-Q1
The LM61460-Q1 device is an easy-to-use synchronous step-down DC/DC converter capable of driving up to 6 A of load current from a supply voltage ranging from 3 V to 36 V. The LM61460-Q1 provides exceptional efficiency and output accuracy in a very small solution size. The LM61460-Q1 is capable of delivering 6 A of load current and is peak current limit controlled. The following are additional features that provide both flexible and easy-to-use solutions for a wide range of applications:
Automatic frequency foldback at light load and optional external bias improve efficiency over the entire load range. The device requires few external components and has a pinout designed for optimal EMI and thermal performance. Protection features include the following:
The LM61460-Q1 device is pin-to-pin compatible with the LM61440-Q1 for easy output current scaling.
For a quick reference, Figure 1-1 shows the pin configuration of the LM61460-Q1 and Figure 1-2 shows the simplified schematic. See the LM61460-Q1 Automotive 3-V to 36-V, 6-A, Low-Noise Synchronous Step-Down Converter Data Sheet for more detailed feature descriptions and design guide.
