| Product Brief, 02-Apr-08 Advanced InformationAll Information Subject to Change ACT6330 Dual PWM Step-Up DC/DCs in TQFN33 FEATURES * Multiple Patents Pending * Two Integrated Regulators - REG1: PWM Step-Up DC/DC with OVP for WLED Bias - REG2: PWM Step-Up DC/DC Converter with OVP GENERAL DESCRIPTION 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. 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. The ACT6330 is available in a tiny 3mm x 3mm 16-pin Thin-QFN package that is just 0.75mm thin. * Independent Enable/Disable Control * Minimal External Components * 3x3mm, Thin-QFN (TQFN33-16) Package - Only 0.75mm Height - RoHS Compliant APPLICATIONS * Portable Devices and PDAs * MP3/MP4 Players * Wireless Handhelds * GPS Receivers SYSTEM BLOCK DIAGRAM Battery REG1 Step-Up DC/DC System Control OUT1 WLED Bias Up to 18 LEDs ON1 ON2 REG2 ACT6330 Active Step-Up DC/DC OUT2 Up to 20V PMU TM Innovative PowerTM ActivePMU TM -1- www.active-semi.com Copyright (c) 2008 Active-Semi, Inc. is a trademark of Active-Semi.
