MP2108DK-LF-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP2108DK-LF-P is a synchronous step-down converter from Monolithic Power Systems. It operates with an input voltage range of 2.6 V to 6 V and delivers up to 2 A output current. The fixed switching frequency is 740 kHz, allowing for compact external component selection. The adjustable output voltage ranges from 900 mV to 5 V. It utilizes a 10-pin MSOP package and functions within a temperature range of -40 °C to +85 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-side and low-side power switches for synchronous rectification to maximize efficiency.
• Includes comprehensive protection mechanisms such as over-temperature shutdown, undervoltage lockout, and cycle-by-cycle current limiting.
• Features soft-start functionality to limit inrush current during startup.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered portable devices
• Industrial control system power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DK' corresponds to the MSOP-10 package variant required for your design. Confirm RoHS compliance status through official datasheets. Check the lifecycle status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure thermal management aligns with the MSOP package limitations for currents exceeding 1.5 A.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2 A synchronous buck solution is needed within a 6 V input window. The 740 kHz frequency balances size and efficiency. Consider the QFN variant if higher current handling or thermal performance is critical, as the MSOP package may require careful layout for loads above 1.5 A. Verify output voltage requirements fall within the 0.9 V to 5 V adjustable range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP2108 series of synchronous buck converters. It is designed for low-voltage, high-efficiency applications. The DK suffix indicates the MSOP-10 package option, distinct from the DQ (QFN) variant. The series emphasizes small form factor solutions through integrated power switches and high-frequency operation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer resources for direct pin-to-pin replacements or evaluate alternative MPS synchronous buck converters with similar electrical specifications.
