General description
The UC3842/UC3843/UC3844/UC3845
are fixed frequency current-mode PWM
controller. They are specially designed
for Off - Line and DC-to-DC converter
applications with minimum external
components. These integrated circuits
feature a trimmed oscillator for precise
duty cycle control, a temperature
compensated reference, high gain error
amplifier, current sensing comparator,
and a high current totempole output
ideally suited for driving a power
MOSFET. Protection circuity Includes
built in under-voltage lockout and
current limiting. The UC3842 and
UC3844 have UVLO thresholds of 16V
(on) and 10V (off) The UC3843 and
UC3845 are 8.5V (on) and 7.9V (off)
The UC3842 and UC3843 can operate
within 100% duty cycle. The UC3844
and UC3845 can operate with 50% duty
cycle.
