MP5611GQT-Z

Overview

The MP5611GQT-Z is a triple-output AMOLED display power supply from Monolithic Power Systems, housed in a TQFN-EP-16 package. It operates with an input voltage range of 2.9 V to 5.2 V and delivers up to 500 mA output current at 5 V. The device utilizes a boost topology with a fixed switching frequency of 1.7 MHz. It features a quiescent current of 1.6 mA and functions reliably within a temperature range of -40 C to +125 C.

Feature Summary

• Provides three distinct output rails specifically engineered for AMOLED display power requirements
• Integrates synchronous rectification to maximize conversion efficiency across the operating range
• Includes comprehensive protection mechanisms such as overcurrent and thermal shutdown

Applications

• AMOLED display panel biasing systems
• Mobile smartphone power management units
• Tablet computer display driver circuits

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm pinout compatibility and thermal pad configuration. Ensure the ordering part number matches the exact tape-and-reel quantity specifications required by your assembly line. Cross-reference the RoHS compliance status directly with the manufacturer's latest certification records before finalizing procurement contracts.

Selection Notes

Select this component when designing for AMOLED displays requiring multiple regulated voltages from a single lithium-ion cell source. The integrated triple-output architecture reduces external component count compared to discrete solutions. Evaluate the 1.7 MHz switching frequency against EMI constraints and inductor size requirements for your specific PCB layout area.

Part Context

This device belongs to the Monolithic Power Systems PMIC portfolio focused on mobile display applications. It addresses the trend toward thinner devices by consolidating multiple power rails into a single compact TQFN-EP-16 package. The series supports modern high-resolution screens that demand precise voltage regulation and low noise performance.

Replacement Considerations

Consult MPS datasheets for direct pin-compatible alternatives within the same family. Verify electrical parameter equivalence for any substitute part numbers before implementation.
