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 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.
