Three-Channel Integrated Power Management IC for
Handheld Portable Equipment
FEATURES
GENERAL DESCRIPTION
The patent-pending ACT8332 is a complete, cost-
• Multiple Patents Pending
efficient ActivePMUTM power management solution
• Three Integrated Regulators
− 350mA PWM Step-Down DC/DC
− 360mA Low Noise LDO
that is ideal for a wide range of portable handheld
equipment. This device integrates a PWM step-
down DC/DC converter and two low-noise, low-
dropout linear regulators (LDOs) into a single, thin,
space-saving package. This device is ideal for a
wide range of portable handheld equipment that
can benefit from the advantages of ActivePMUTM
technology but does not require a high level of inte-
gration.
− 360mA Low Noise LDO
• Independent Enable/Disable Control
• Minimal External Components
• 3x3mm, Thin-DFN (TDFN33-10) Package
REG1 is a fixed-frequency, current-mode PWM
step-down DC/DC converter that is optimized for
high efficiency and is capable of supplying up to
350mA. REG1’s output is available in a variety of
factory-preset output voltage, and an adjustable
output voltage mode is also available. REG2 and
REG3 are low noise LDOs that are available in a
variety of fixed output voltage options and are each
capable of supplying up to 360mA.
− Only 0.75mm Height
− RoHS Compliant
APPLICATIONS
• Portable Devices and PDAs
• MP3/MP4 Players
• Wireless Handhelds
• GPS Receivers
The ACT8332 is available in a tiny 3mm x 3mm
10-pin Thin-DFN package that is just 0.75mm thin.
