The CS284XA, CS384XA provides all
the necessary features to implement
off-line fixed frequency current-mode
control with a minimum number of
external components.
The CS384XA family incorporates a
new precision temperature-controlled
oscillator with an internally trimmed
discharge current to minimize varia-
tions in frequency. A precision duty-
cycle clamp eliminates the need for an
external oscillator when a 50% duty-
cycle is used. Duty-cycles greater than
50% are also possible. On board logic
ensures that VREF is stabilized before
the output stage is enabled. Ion
implant resistors provide tighter con-
trol of undervoltage lockout.
Other features include low start-up
current, pulse-by-pulse current limit-
ing, and a high-current totem pole out-
put for driving capacitive loads, such
as the gate of power MOSFET. The out-
put is LOW in the off state, consistent
with N-channel devices.
The CS384XA series of current-mode
control ICs are available in 8 and14
lead packages for surface mount (SO)
applications as well as 8 lead PDIP
packages.
