MP26056DQ-LF-P

Battery Chargers Overview

The MP26056DQ-LF-P is a synchronous buck-boost DC/DC converter manufactured by Monolithic Power Systems. It operates with an input voltage range of 2.7V to 18V and provides a regulated output voltage of 4.2V. The device supports an output current of up to 1A and functions within an ambient temperature range of -40°C to +85°C. It utilizes a QFN-16 package for surface mount installation.

Battery Chargers Feature Summary

• Synchronous buck-boost topology for wide input voltage compatibility
• Integrated power switches for high conversion efficiency
• Fixed 4.2V output suitable for single-cell lithium battery charging

Battery Chargers Applications

• Single-cell lithium-ion or lithium-polymer battery charging systems
• Portable electronic devices requiring wide input voltage ranges
• USB-powered applications with variable source voltages

Battery Chargers Procurement Notes

Verify the specific suffix 'P' against the manufacturer datasheet to confirm packaging type, as suffixes often denote tape-and-reel quantities versus cut tape. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the full part number with official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Battery Chargers Selection Notes

Select this component when a linear charger is insufficient due to high input-output voltage differentials. The buck-boost architecture allows operation from sources lower than, equal to, or higher than the battery voltage. Consider the thermal performance in the QFN-16 package relative to the expected load current and PCB copper area for adequate heat dissipation.

Battery Chargers Part Context

This part belongs to the MP2605x series of battery management ICs from Monolithic Power Systems. Unlike the linear MP26053 or MP26023 models found in related data, this device employs switching regulation. It serves as a more efficient alternative for applications where input voltage stability cannot be guaranteed or varies significantly above and below the target charge voltage.

Battery Chargers Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in the provided documentation. Similar MPS linear chargers like the MP26053 offer fixed functionality but lack the wide input range. Verify electrical compatibility and thermal characteristics carefully if substituting with other buck-boost controllers.
