MP161AGS-5-Z

Overview

The MP161AGS-5-Z is a specialized power management IC from Monolithic Power Systems, designed as a non-isolated buck regulator with ultra-low standby power consumption. It integrates a switching regulator and an LDO to provide multiple outputs, specifically targeting smart plug applications. The device operates within a temperature range of -40°C to +125°C and features a SOIC-16 package. Key electrical parameters include a maximum output voltage of 5.1 V, an operating supply current of 600 uA, and a power dissipation of 1.56 W.

Feature Summary

• Integrates a switching regulator with current limiting for efficient power conversion
• Features ultra-low standby power consumption suitable for always-on applications
• Includes an integrated LDO for stable auxiliary voltage generation

Applications

• Smart plug reference designs
• Non-isolated offline power supplies
• IoT devices requiring low quiescent current

Procurement Notes

Verify the specific suffix 'Z' against official MPS documentation to confirm RoHS compliance status and exact pinout configuration relative to other variants like the 'P' suffix. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet before procurement.

Selection Notes

Select this component when designing systems that require a compact, non-isolated solution with minimal no-load power draw. The SOIC-16 package offers a balance between thermal performance and board space efficiency compared to smaller footprints, while the integrated protection features simplify external component selection.

Part Context

This part belongs to the MP161 series of specialized PMICs from Monolithic Power Systems. It is distinct from the MP163 series, which targets higher power offline applications up to 700V. The MP161 series focuses on low-power, high-efficiency regulation for consumer electronics and smart home devices.

Replacement Considerations

The MP161BGS-5-P is a related variant within the same family offering different current capabilities. Verify functional equivalence and pin compatibility before substitution, as output current limits may differ between the A and B suffixes.
