Overview
The LT3972IMSE#PBF is a monolithic synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 33V and delivers up to 3.5A of output current. The device features a fixed switching frequency of 2.45MHz, allowing for the use of small external components. Quiescent current consumption is specified at 75µA during operation and drops to 30µA in shutdown mode. The output voltage is adjustable from 790mV to 30V. It is housed in a thermally enhanced 10-lead MSOP package.
Feature Summary
- Synchronous step-down topology integrates high-side and low-side power switches for improved efficiency.
Applications
- Distributed power supplies in industrial equipment.
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering part number matches the exact package variant required for your PCB footprint design.
Selection Notes
Select this component when a wide input voltage range up to 33V is required alongside moderate current delivery. The fixed 2.45MHz frequency supports compact passive component selection. Evaluate thermal performance requirements based on the MSOP package limitations under full load conditions.
Part Context
This part belongs to the LT3972 family of high-voltage synchronous buck regulators. It shares architectural similarities with other members like the LT3971 and LT3973 but offers distinct current handling and input voltage specifications tailored for mid-power applications requiring efficient DC-DC conversion.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the same product family or equivalent performance tiers from other manufacturers.
