TECHNICAL DATA
Fixed Frequency Current Mode PWM Controller
IL3842
DESCRIPTION
Fixed frequency current-mode PWM controller. It is specially designed for
Off Line And DC-to-DC converter applications with minimal external
component. This integrated circuit features a trimmed oscillator for precise duty
cycle control. a temperature compensated reference, high gain arror amplifier,
current sensing comparator, and a high current totempole output ideally suited
for driving a power MOSFET.
Protection circuitry includes built in under-voltage lockout and current
limiting.
