ACT6330 Product Brief, 02-Apr-08 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 SYSTEM BLOCK DIAGRAM REG1 Battery ON1 Step-Up DC/DC OUT1 WLED Bias Up to 18 LEDs System Control ON2 REG2 Step-Up DC/DC ACT6330 PMU OUT2 Up to 20V TM Active Innovative PowerTM ActivePMU TM is a trademark of Active-Semi. -1- www.active-semi.com Copyright © 2008 Active-Semi, Inc.
