MP5611

2.9V to 5.2V Input, Triple-Output,

AMOLED Display Power Supply

DESCRIPTION

FEATURES

The MP5611 is a triple-output converter across

a 2.9 to 5.2V input voltage (V_IN) range designed

for small-size AMOLED (active matrix organic

light-emitting diode) display power supplies.

•

2.9 to 5.2V Input Voltage (V_IN) Range

Triple Output AVDD, ELVDD, ELVSS

High Accuracy for Output Voltage (V_OUT

Good Line and Load Regulation

Configurable V_ELVDD= 4.6V to 5.2V, Default

4.6V

Configurable V_ELVSS= -1.4V to -6.4V,

Default -4V

500mA Output Current (I_OUT) for ELVDD and

ELVSS

Configurable V_AVDD= 5V to 7.7V, Default

5.8V

100mA I_OUTfor AVDD

Respective Enable for AVDD and ELVDD

Soft Start (SS)

Active Fast Discharge Function

Cycle-by-Cycle Current Limit Protection

AVDD Output Over-Current Protection

(OCP) 90mA to 270mA

)

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

V_INunder-voltage lockout (UVLO), cycle-by-

cycle current limit protection, thermal shutdown

protection, short output protection, and over-

current protection (OCP) for AVDD and ELVDD.

•

ELVDD Output OCP 80mA to 650mA

Output Short-to-GND Protection

Over-Temperature Protection (OTP)

Available in a TQFN-16 (3mmx3mm)

Package

The fully integrated synchronous rectification

solution with low on resistance improves total

system

efficiency,

minimizes

external

components, and reduces PCB layout size.
