Dual PWM Step-Down DC/DCs in TDFN33

FEATURES

GENERAL DESCRIPTION

The patent-pending ACT8325 integrates two step-

down DC/DCs into a single, thin, space-saving

• Multiple Patents Pending

• Two Integrated Step-Down DC/DC Converters

− REG1: 350mA

− REG2: 550mA

package to provide a cost-effective, highly-efficient

ActivePMU^TMpower management solution. This

device is ideal for a wide range of portable hand-

held equipment that can benefit from the advan-

tages of ActivePMU technology but do not require a

high level of integration.

• 180° Out-of-Phase Operation

− Reduces Input Capacitor Requirements

• Fixed or Adjustable Output Voltage Options

REG1 and REG2 are fixed-frequency, current-mode

PWM step-down DC/DC converters that are opti-

mized for high efficiency and are capable of supply-

ing up to 350mA and 550mA, respectively. Both

outputs are available in a wide range of factory-

preset output voltage options, and an adjustable

output voltage mode is also available.

• Independent Enable/Disable Control

• Minimal External Components

• 3x3mm, Thin-DFN (TDFN33-10) Package

− Only 0.75mm Height

− RoHS-Compliant

The ACT8325 is available in a tiny 3mm x 3mm

10-pin Thin-DFN package that is just 0.75mm thin.

APPLICATIONS

• Portable Devices and PDAs

• MP3/MP4 Players

• Wireless Handhelds

• GPS Receivers
