EV5611-QT-00A

EV5611-QT-00A is a 2.9V to 5.2V input, triple-output, AMOLED display power supply evaluation board. The MP5611 is a triple-output converter with a 2.9V to 5.2V input voltage (VIN) 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. Typical applications include AMOLED smartphones and AMOLED displays.

• 2.9V to 5.2V input voltage (VIN) range
• Triple output AVDD, ELVDD, and ELVSS
• High accuracy for output voltage (VOUT), good line and load regulation
• Configurable VELVDD = 4.6 to 5.2V, default 4.6V and configurable VELVSS = -1.4 to -6.4V, default -4V
• 500mA Output Current (IOUT) for ELVDD, ELVSS and configurable VAVDD = 5V to 7.7V, default 5.8V
• 100mA IOUT for AVDD and soft start (SS)
• Separate enable pins for AVDD and ELVDD
• Active fast discharge function and cycle-by-cycle current limit protection
• 90mA to 270mA AVDD Output Overcurrent protection (OCP) and 80mA to 650mA ELVDD output OCP
• Output short-to-GND protection and Over-Temperature Protection (OTP)
