DESCRIPTION
The UCC3806 family of BiCMOS PWM controllers
offers exceptionally improved performance with a
familiar architecture. With the same block diagram
and pinout of the popular UC3846 series, the
UCC3806 line features increased switching
frequency capability while greatly reducing the
bias current used within the device. With a typical
startup current of 50 μA and a well defined voltage
threshold for turn-on, these devices are favored
for applications ranging from off-line power
supplies to battery operated portable equipment.
Dual high-current, MOSFET driving outputs and a
fast current sense loop further enhance device
versatility.
All the benefits of current mode control including
simpler loop closing, voltage feed-forward,
parallelability with current sharing, pulse-by-pulse
current
limiting,
and
push/pull
symmetry
correction are readily achievable with the
UCC3806 series.
These devices are available in multiple package
options for both through-hole and surface mount
applications; and in commercial, industrial, and
military temperature ranges.
The UCC1806 is specified for operation from
--55°C to 125°C, the UCC2806 is specified for
operation from --40°Cto85°C, and the UCC3806
is specified for operation from 0°Cto70°C.
