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
mlimiting.
.coFEATURES
♦ Automatic Feed Forward Compensation
♦High Gain Totem Pole Output
U♦Internally Trimmed Bandgap Reference
t4♦Undervoltage Lockout with Hysteresis
♦Low Start Up Current
e♦Optimized for offline converter
♦Double pulse suppression
e♦Current mode operation to 500KHz
