GENERAL DESCRIPTION

The ACT5880 is a complete, cost effective, highly-

efficient ActivePMUTM power 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 a

complete battery charging solution.

This device also integrates a touch screen

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.

The ACT5880 is available in a compact, Pb-Free

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

FBGA package with 1mm height.
