MP5611GQT-P

Overview

The MP5611GQT-P is a switching voltage regulator from Monolithic Power Systems designed for AMOLED display power supplies. It operates with an input voltage range of 2.9 V to 5.2 V and provides a fixed 5 V output capable of delivering up to 500 mA. The device utilizes a boost topology with a typical switching frequency of 1.7 MHz. It features a low static current of 1.6 mA and functions within a temperature range of -40 °C to +125 °C. The component is housed in a TQFN-EP-16 package suitable for surface mount installation.

Feature Summary

• Integrated boost converter architecture optimized for AMOLED display biasing applications
• Fixed 5 V output regulation with high efficiency performance characteristics
• Built-in protection mechanisms including over-temperature shutdown and current limiting

Applications

• AMOLED display power supply systems
• Mobile device display bias circuits
• Portable electronics requiring stable 5V rails

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm packaging configuration, as suffixes often denote reel or cut tape variations. Ensure the order matches the required quantity increments specified by the manufacturer for the selected packaging type. Cross-reference the datasheet revision date to guarantee compatibility with current design specifications and regulatory compliance standards.

Selection Notes

Select this component when a compact boost solution is required for AMOLED displays operating between 2.9 V and 5.2 V. The 1.7 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the TQFN-EP-16 package for thermal management and space-constrained PCB layouts. Verify that the 500 mA output current meets the specific load requirements of the target display panel.

Part Context

This part belongs to the Monolithic Power Systems PMIC portfolio, specifically categorized under switching regulators. It is related to other display power solutions such as the MP5610, which offers dual-channel capabilities for LCD biasing. The MP5611 series addresses the specific needs of active matrix organic light-emitting diode technologies, providing dedicated voltage regulation distinct from general-purpose DC-DC converters.

Replacement Considerations

Consult official MPS substitution guides for verified equivalents. Generic replacements may not match the specific AMOLED biasing requirements or pinout configurations.
