MP5611GQT-P

MP5611 is a triple-output converter across a 2.9 to 5.2V input voltage (VIN) range designed for small-size AMOLED (active matrix organic light-emitting diode) 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 the separated 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 VIN under-voltage lockout (UVLO), cycle-by cycle current limit protection, thermal shutdown protection, short output protection, and overcurrent protection (OCP) for AVDD and ELVDD. Applications include AMOLED smartphones, AMOLED displays.
