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
