Six Channel Integrated Power Management IC

for Handheld Portable Equipment

FEATURES

• Multiple Patents Pending

• Six Integrated Regulators

− 750mA PWM Step-Down DC/DC

− 550mA PWM Step-Down DC/DC

− 250mA Low Noise LDO

• I²C^TMCompatible Serial Interface

− Programmable Output Voltages

− Configurable Operating Modes

GENERAL DESCRIPTION

The patent-pending ACT8796 is a complete, cost-

effective, highly-efficient ActivePMU^TMpower

management solution that is ideal for a wide range

of portable handheld equipment. This device

integrates 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,

current-mode PWM step-down DC/DC converters

that are optimized for high efficiency and are

capable of supplying up to 750mA, 750mA and

550mA, respectively. REG4, REG5 and REG6 are

low noise, high PSRR linear regulators that are

• Minimal External Components

• 4x4mm, Thin-QFN (TQFN44-24) Package

− Only 0.75mm Height

capable of supplying up to 250mA each.

− RoHS Compliant

The ACT8796 is available in a tiny 4mm×4mm 24-

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

APPLICATIONS

• Portable Devices and PDAs

• Wireless Handhelds

• DMB Enabled Devices

• GPS Receivers, etc.
