Advanced Information―All Information Subject to Change
Dual PWM Step-Up DC/DCs in TQFN33
FEATURES
GENERAL DESCRIPTION
• Multiple Patents Pending
The patent-pending ACT6330 integrates two stepup DC/DCs into a single, thin, space-saving package to provide a cost-effective, highly-efficient
ActivePMUTM power management solution. This
device is ideal for a wide range of portable handheld equipment that can benefit from the advantages of ActivePMU technology but does not require a high level of integration.
• Two Integrated Regulators
− REG1: PWM Step-Up DC/DC with OVP for
WLED Bias
− REG2: PWM Step-Up DC/DC Converter with
OVP
• Independent Enable/Disable Control
REG1 and REG2 are fixed-frequency, current-mode
PWM step-up DC/DC converters. REG1 is optimized for high-efficiency WLED bias applications.
REG2 is optimized for voltage regulation applications, while together these outputs can provide a
complete TFT bias and backlighting solution for
portable handheld equipment.
• Minimal External Components
• 3x3mm, Thin-QFN (TQFN33-16) Package
− Only 0.75mm Height
− RoHS Compliant
The ACT6330 is available in a tiny 3mm x 3mm
16-pin Thin-QFN package that is just 0.75mm thin.
APPLICATIONS
• Portable Devices and PDAs
• MP3/MP4 Players
• Wireless Handhelds
• GPS Receivers
