Monolithic Power Systems (MPS) MP5611 Triple-Output Converters

Monolithic Power Systems (MPS) MP5611 Triple-Output Converters are designed for small-size Active Natrix Organic Light-Emitting Diode (AMOLED) display power supplies. These converters integrate a boost converter for AVDD, and ELVDD, an Inverting Buck-Boost (IBB) converter for ELVSS. The MP5611 converters support an independent start-up sequence for AVDD and ELVDD via the separated enable pins (EN_AVDD and CTRL). These converters feature Soft Start (SS), active fast discharge function, cycle-by-cycle current limit protection, Under-Voltage Lockout (UVLO), thermal shutdown protection, and 2.9V to 5.2V input voltage. The MP5611 converters are available in a TQFN-16 (3mm x 3mm) package and can be used in AMOLED smartphones and displays.
