GENERAL DESCRIPTION

The patent-pending ACT8780 is a complete, cost-

effective, highly-efficient

ActivePMU

power man-

agement solution that is ideal for a wide range of

portable handheld equipment. This device inte-

grates three step-down DC/DC converters and

three low dropout linear regulators (LDOs) into a

single, thin, space-saving package. An I

C Serial

Interface provides programmability for the DC/DC

converters and LDOs.

The ACT8780 also integrates two enable pins: ON1

controls REG1, REG2 and REG3, ON4 controls

REG4, REG5 and REG6.

REG1, REG2 and REG3 are fixed-frequency, cur-

rent-mode PWM step-down DC/DC converters that

are optimized for high efficiency and are capable of

supplying up to 350mA, 550mA and 550mA, re-

spectively. REG4, REG5 and REG6 are low noise,

high PSRR linear regulators that are capable of

supplying up to 250mA each.

The ACT8780 is available in a tiny 4mm x 4mm

24-pin Thin-QFN package that is just 0.75mm thin.
