15 Channels Advanced PMU for Smart Phone

FEATURES

GENERAL DESCRIPTION

The ACT5880 is a complete, cost effective, highly-

• Flexible CCCV Charger with Internal MOSFET

− Programmable Charge Current

− Programmable Charge Termination Voltage

− Programmable OVP threshold

− Regulation against Die Thermal Condition

− Charge Status Output, LED driving

− Battery Thermal Condition Monitor

− Battery Installation Detection

efficient ActivePMU^TMpower management solution,

optimized for portable devices like smart phones,

Mobile Internet Devices.

This device features two step-down DC/DC

converters, one step-up DC/DC regulator, seven

high PSRR LDOs, three low quiescent current

LDOs, one always-on LDO, and one back-up

battery/super-capacitor charger, along with

complete battery charging solution.

− USB Charging Compatible

This device also integrates

touch screen

• Fifteen Channels of Power Supplies

− Two Step-Down DC/DC Converters

− One Step-up Regulator, ~40V, ~750mA Switch

− Seven High PSRR LDOs

− Three Low Quiescent Current LDOs

− One Always-on LDO

controller interface with three AUX inputs, three

current controlled LED drivers, and a Real Time

Clock.

The two step-down DC/DC converters utilize a high

efficiency, fixed-frequency (2MHz), current-mode

PWM control architecture that requires a minimum

number of external components. Two step-down

DC/DCs are capable of supplying up to 1200mA

and 700mA of output current. All LDOs are high-

performance, low-noise, regulators that supply up to

360mA of output current. The back-up battery

charger supports up to 3.5mA of output current.

− One Back-up Battery/Super-Capacitor Charger

• Advanced System Control and Interfaces

− I²C^TMSerial Interface

− Touch Screen Controller with Three AUX Inputs

• Advanced Function

− Real Time Clock

− Three CC/PWM LED Drivers, ODO1 Supports up

to 40V

The ACT5880 is available in a compact, Pb-Free

and RoHS-compliant, 81 balls, 6mmx6mm FC-

FBGA package with 1mm height.
