1 / 5 page TECHNICAL DATA 2011, February, Rev. 03 Fixed Frequency Current Mode PWM Controller 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 . FEATURES ♦ Automatic Feed Forward Compensation ♦High Gain Totem Pole Output ♦Internally Trimmed Bandgap Reference ♦Undervoltage Lockout with Hysteresis ♦Low Start Up Current ♦Optimized for offline converter ♦Double pulse suppression ♦Current mode operation to 500KHz ORDERING INFORMATION IL3843 ORDERI NG I NFORM ATI ON IL3843N Plastic IL3843D SOIC T A = 0 ° to 70° C for all packages.
