MP8709EN-LF-P

Voltage Regulators - DC DC Switching Regulators Overview

The MP8709EN-LF-P is a synchronous step-down DC-DC converter manufactured by Monolithic Power Systems. It integrates high-side and low-side N-channel MOSFETs to deliver a continuous output current of 4A. The device operates with an input voltage range up to 21V and supports adjustable output voltages starting from 0.8V. It features a fixed switching frequency of 500kHz, enabling the use of small external components. The IC includes comprehensive protection features such as over-current protection, thermal shutdown, and under-voltage lockout.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'P' against the official datasheet to confirm packaging details, as standard listings often default to 'Z'. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation. Ensure the lead time and availability align with project requirements, as supply chain conditions for this component may vary. Cross-reference the exact part number to avoid confusion with similar MPS buck converters.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 4A output current is required within a compact SOIC-8 footprint. It is suitable for designs needing a 500kHz switching frequency to balance efficiency and component size. Consider the 21V maximum input rating for general-purpose applications. Evaluate thermal performance based on the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP8709 family of synchronous buck converters from Monolithic Power Systems. It shares architectural similarities with other MPS devices like the MP8718 but is distinguished by its specific current rating and package configuration. The series is designed for cost-sensitive applications requiring reliable step-down conversion without external driver components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the MP8709EN-LF-Z for identical electrical specifications with different packaging. For pin-compatible alternatives, consider the MP8718EN-LF-P, which offers similar performance characteristics. Verify that any replacement maintains the same 4A current capability and 21V input limit.
