MP6302DD-LF-Z

Overview

The MP6302DD-LF-Z is a synchronous step-down DC-DC converter manufactured by Monolithic Power Systems. It operates with an input voltage range of 4.5V to 18V and delivers up to 2A output current. The device integrates a high-side N-channel MOSFET and features a fixed switching frequency of 1.5MHz. It utilizes a compact 10-QFN (3x2mm) package, suitable for space-constrained applications requiring efficient power regulation.

Feature Summary

• Integrates high-side N-channel MOSFET for efficient power conversion
• Fixed 1.5MHz switching frequency reduces external component size
• Supports adjustable output voltage via external resistor divider
• Includes comprehensive protection against overcurrent and thermal overload

Applications

• Portable electronics battery-powered systems
• Embedded industrial control modules
• Communication equipment power distribution
• Consumer gadget voltage regulation

Procurement Notes

Verify the specific suffix 'LF-Z' indicates lead-free and halogen-free compliance per MPS standards. Confirm the 10-QFN package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when input voltages exceed 4.5V and require stable 2A regulation. The fixed 1.5MHz frequency optimizes inductor size compared to lower-frequency alternatives. Consider the QFN package for surface-mount assembly constraints and thermal dissipation needs in dense layouts.

Part Context

This IC belongs to the MP6302 series of synchronous buck converters designed for medium-current applications. It represents MPS's approach to integrating power switches within a small footprint, distinguishing it from discrete solutions or higher-voltage regulator families.

Replacement Considerations

MP6302DD-LF-P is listed as a parameter-equivalent substitute by distributors.
