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
ActivePMU
TM
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.
