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
- 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 GENERAL DESCRIPTION The patent-pending ACT6330 integrates two step- up DC/DCs into a single, thin, space-saving pack- age to provide a cost-effective, highly-efficient ActivePMU TM power 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 does not re- quire a high level of integration. REG1 and REG2 are fixed-frequency, current-mode PWM step-up DC/DC converters. REG1 is opti- mized for high-efficiency WLED bias applications. REG2 is optimized for voltage regulation applica- tions, 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.
