The MP5611 is a triple-output converter with a 2.9V to 5.2V input voltage (V_IN) range designed for small-size active matrix organic light-emitting diode (AMOLED) display power supplies.

The MP5611 integrates a boost converter for ELVDD, an inverting buck-boost (IBB) converter for ELVSS, and another boost converter for AVDD. The one wire digital control pin (CTRL) can program the ELVSS, ELVDD, and AVDD voltages following digital protocol.

The MP5611 supports an independent start-up sequence for AVDD and ELVDD via separate enable pins (EN_AVDD and CTRL). It also integrates an optional fast discharge function after the IC has been disabled.

The device features rich protections, including V_IN under-voltage lockout (UVLO), cycle-by-cycle current limit protection, thermal shutdown protection, short output protection, and over-current protection (OCP) for AVDD and ELVDD.

The fully integrated synchronous rectification solution with low on resistance (R_DS(ON)) improves total system efficiency, minimizes external components, and reduces PCB layout size.

The MP5611 is available in a TQFN-16 (3mmx3mm) package.
