Voltage Regulators - DC DC Switching Regulators datasheet and documents for MP8709EN-LF-Z

MP8709EN-LF-Z

Voltage Regulators - DC DC Switching Regulators Overview

The MP8709EN-LF-Z is a synchronous step-down switching regulator from Monolithic Power Systems. It operates with an input voltage range of 4.5 V to 21 V and delivers up to 4 A of output current. The device features a fixed 500 kHz switching frequency and supports adjustable output voltages starting from 800 mV. It includes soft start functionality and is housed in an 8-lead SOIC package with an exposed pad, suitable for surface-mount applications within a -20°C to +85°C temperature range.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous buck topology for high efficiency
Integrated soft start capability
Fixed 500 kHz switching frequency

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment power stages
General-purpose DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LF-Z' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance. Confirm availability status as distribution channels may indicate limited supply or end-of-life conditions. Ensure the SOIC-EP-8 footprint matches the target PCB design requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 4 A current capacity and 21 V maximum input voltage are required. The 500 kHz frequency offers a balance between component size and efficiency. Verify that the minimum output voltage requirement aligns with the 800 mV floor. Consider thermal performance in the SOIC-EP-8 package for the intended ambient operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP8709 series of synchronous buck converters. It shares architectural similarities with other MPS regulators but is distinguished by its specific 4 A rating and 21 V input limit. The family focuses on compact power solutions for portable and industrial applications requiring reliable step-down conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives. Verify electrical parameter compatibility including input voltage range and output current capabilities before replacing.
