GENERAL DESCRIPTION

The patent-pending ACT8798 is a complete, cost-

effective, highly-efficient ActivePMUTM 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 I2C Serial

Interface provides programmability for the DC/DC

converters and LDOs.

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 1.2A, 1.2A and 750mA, respec-

tively. REG4, REG5 and REG6 are low noise, high

PSRR linear regulators that are capable of supply-

ing up to 250mA each.

The ACT8798 is available in a tiny 4mm x 4mm 24-

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