MAX16140B220KM+T

Supervisors Overview

The MAX16140B220KM+T is a high-efficiency, synchronous step-down DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It integrates two power switches and operates from an input voltage range of 3V to 28V. The device delivers a programmable output voltage with a maximum load current capability of 5A. Key electrical parameters include a switching frequency selectable between 400kHz and 2MHz, and a quiescent current of 170µA during active operation. It features a low standby current of 10µA in shutdown mode. The component is housed in a thermally enhanced 10-pin, 3mm x 3mm TDFN package, suitable for space-constrained applications requiring robust power management.

Supervisors Procurement Notes

Verify the suffix '+T' indicates tape and reel packaging configuration. Confirm the 'B220' designation matches the specific output voltage setting or internal resistor network requirements. Ensure the 'KM' package code aligns with the required thermal pad dimensions. Check RoHS compliance status as indicated by the '+' suffix. Validate that the manufacturer source is Analog Devices Inc. or Maxim Integrated.

Supervisors Selection Notes

Select this component when a wide input voltage range up to 28V is required alongside high output current capabilities. Consider the adjustable switching frequency feature if electromagnetic interference (EMI) constraints necessitate frequency detuning. Evaluate the thermal performance of the TDFN package against the expected ambient temperature and load conditions. Compare quiescent current specifications against system power budget requirements for both active and shutdown states.
