ACT6330 Dual PWM Step-Up DC/DCs in TQFN33 Rev0, 02-Apr-08 SYSTEM BLOCK DIAGRAM FEATURES • Multiple Patents Pending • Two Integrated Regulators − PWM Step-Up DC/DC with OVP for WLED Bias − PWM Step-Up DC/DC Converter with OVP • Independent Enable/Disable Control • Minimal External Components • 3×3mm, Thin-QFN (TQFN33-16) Package − Only 0.75mm Height − RoHS Compliant APPLICATIONS • Portable Devices and PDAs • MP3/MP4 Players • Wireless Handhelds • GPS Receivers GENERAL DESCRIPTION The patent-pending ACT6330 integrates two step- up DC/DC 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 tech- nology but does not require a high level of integra- tion. REG1 and REG2 are fixed-frequency, current mode PWM step-up DC/DC converter. REG1 is optimized for high-efficiency WLED bias applications. REG2 is optimized for voltage regulation applications, while together these output 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. ON2 OUT1 WLED Bias Up to 18 LEDs OUT2 Up to 20V ON1 REG2 Step-Up DC/DC REG1 Step-Up DC/DC System Control Battery ACT6330 TM PMU PMU Active Pb-free |
