MP4013BGS-P

Overview

The MP4013BGS-P is a synchronous step-down DC/DC converter from Monolithic Power Systems. It integrates high-side and low-side N-channel power MOSFETs to deliver efficient voltage regulation. The device operates with an input voltage range of 2.7V to 5.5V, supporting outputs up to 3A. It features fixed-frequency operation at 1MHz or 2.25MHz, selectable via the SYNC pin. Internal compensation ensures stability with small external ceramic capacitors. The converter includes comprehensive protection mechanisms such as over-current protection, thermal shutdown, and undervoltage lockout for reliable system performance.

Feature Summary

• Integrated synchronous rectification with internal high-side and low-side N-channel MOSFETs
• Fixed switching frequency operation selectable between 1MHz and 2.25MHz
• Internal compensation network designed for stable operation with minimal external components
• Comprehensive protection including cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout

Applications

• Portable electronics requiring efficient power management
• Embedded systems with single-supply requirements
• Battery-powered devices needing extended runtime
• Industrial control modules with space-constrained layouts

Procurement Notes

Verify the exact suffix 'P' indicates the specific tape-and-reel packaging configuration when ordering. Confirm that the B-grade binning matches your thermal and electrical tolerance requirements. Ensure the order quantity aligns with standard reel sizes provided by authorized distributors. Cross-reference the date code to ensure component freshness and storage integrity prior to assembly.

Selection Notes

Choose this component when space efficiency and high switching frequencies are prioritized over ultra-low quiescent current. The integrated MOSFETs reduce board area compared to discrete solutions. Verify that the load current does not exceed the 3A limit under worst-case thermal conditions. Consider the output voltage setting resistor values to ensure accuracy within specified tolerances for sensitive logic loads.

Part Context

This part belongs to the MP40xx series of synchronous buck converters. It shares architectural similarities with other models in the lineup but differs in specific current ratings and package dimensions. The GSSOP-8 package provides a compact footprint suitable for dense PCB layouts. It complements higher-power variants in the same family by offering a balance between size and performance for mid-range applications.

Replacement Considerations

Direct substitutes include the MP4013AGS-P for A-grade binning variations. The MP4013CGS-P may be considered if C-grade specifications are acceptable. Check pin compatibility and thermal pad connections before swapping. Verify that the replacement part supports the same switching frequency selection options.
