MP8715DN-LF

Voltage Regulators - DC DC Switching Regulators Overview

The MP8715DN-LF is a synchronous step-down converter from Monolithic Power Systems. It operates with an input voltage range of 4.5V to 21V and delivers a continuous output current of 4A. The device features a fixed switching frequency of 500kHz and supports 100% duty cycle operation, allowing the output voltage to track down to the input level. Integrated power MOSFETs include a 120mΩ high-side switch and a 50mΩ low-side synchronous rectifier. The adjustable output voltage ranges from 0.8V to VIN.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates internal high-side and low-side power MOSFETs for high efficiency without external Schottky diodes
• Supports 100% duty cycle operation to maintain regulation at low dropout voltages
• Provides stable operation using only ceramic output capacitors
• Includes power good indicator and external soft-start capability for flexible system control

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial equipment
• Power supply stages for embedded computing systems
• Voltage conversion for communication infrastructure modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature rating. Ensure the ordering code matches the required thermal performance and pin configuration. Cross-reference the component marking with official MPS documentation to prevent counterfeit substitution during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 4A loads within a 21V input limit. The 500kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the application requires ceramic capacitor stability and does not need the higher current capacity of the MP8712 series.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP8715 family of synchronous buck converters designed for medium-power applications. It shares architectural similarities with other MPS devices but is distinct in its 4A current rating and 21V maximum input specification. The DN suffix typically denotes an SOIC-EP package variant.
