MP161BGS-5-P

Overview

The MP161BGS-5-P is a specialized PMIC from Monolithic Power Systems designed for ultra-low standby power applications. It integrates a switching regulator with a 420mA current limit, delivering a regulated 5V output (range 4.9V to 5.1V) from a 3V to 5.5V input. The device operates within a temperature range of -40°C to +125°C and consumes only 600µA of supply current. Packaged in a 16-SOIC surface-mount format, it offers 1.56W power dissipation capability.

Feature Summary

• Integrates a non-isolated buck regulator with built-in current limiting
• Optimized for ultra-low standby power consumption in smart devices
• Provides stable voltage regulation suitable for sensitive logic loads

Applications

• Smart plug reference designs
• Home appliance power management
• IoT node power supplies

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging when ordering. Confirm the 16-SOIC package dimensions match your PCB footprint constraints. Ensure design accounts for the specified thermal dissipation limits under maximum load conditions. Check moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component for systems requiring minimal quiescent current alongside moderate output current capabilities. Compare against the MP161AGS variant if lower current limits suffice. Validate input voltage stability within the 3V to 5.5V window to ensure proper regulation performance.

Part Context

This part belongs to the MP161 family of specialized PMICs focused on energy efficiency. It serves as a compact solution for replacing linear regulators in battery-powered or always-on smart home devices where standby power reduction is critical.

Replacement Considerations

The MP161AGS-5-P is a related variant with a 240mA current limit. Verify if the reduced current capacity meets system requirements before substituting.
