MP24971DN-LF

Voltage Regulators - DC DC Switching Regulators Overview

The MP24971DN-LF is a non-synchronous buck switching regulator manufactured by Monolithic Power Systems. It operates with an input voltage range of 8 V to 50 V and provides a fixed output voltage of 5 V at a maximum output current of 1.5 A. The device features a fixed switching frequency of 100 kHz and includes shutdown functionality. It is housed in an SOIC-EP-8 package and supports surface mount installation. The component functions within a temperature range of -40°C to +125°C, with a typical quiescent current of 1.2 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Non-synchronous step-down topology for efficient voltage conversion
• Integrated power switch capable of delivering 1.5 A continuous output
• Fixed 100 kHz switching frequency reduces external component size
• Shutdown pin enables low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial equipment
• Power supply stages in consumer electronics
• Battery-powered devices requiring stable 5 V rails
• Embedded systems with wide input voltage variations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DN-LF against official MPS documentation to confirm package type and lead-free status. Confirm end-of-life status as sources indicate discontinuation. Ensure compatibility with existing PCB footprints for SOIC-EP-8 packages. Check for moisture sensitivity levels if storage duration exceeds manufacturer recommendations. Validate that fixed 5 V output meets system requirements without additional adjustment components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs up to 50 V. The non-synchronous design suits applications where efficiency gains from synchronous rectification are not critical. Consider the 1.5 A current limit for load requirements. The SOIC-EP-8 package offers thermal performance benefits over standard SOIC-8. Verify that the 100 kHz frequency aligns with EMI constraints and inductor selection guidelines.

Voltage Regulators - DC DC Switching Regulators Part Context

The MP24971 belongs to the MP24971 series of monolithic buck converters. It shares architectural similarities with other MPS non-synchronous regulators but is distinguished by its fixed 5 V output and 1.5 A rating. The series targets cost-sensitive applications requiring reliable step-down conversion. The DN-LF designation indicates a specific tape-and-reel or tube packaging option depending on distributor data, though official datasheets define the core electrical characteristics.
