DESCRIPTION
The AMC3842B/43B/44B/45B are fixed frequency current-mode PWM controllers specially designed for OFF-Line switching power supply and DC-to-DC converters with a minimum number of external components. These devices feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totempole output which is suitable for driving MOSFETs.
FEATURES
?● Low Start-Up current (max. 200μA)
?● Optimized for Off-Line and DC-to-DC Converters
?● Maximum Duty Cycle
?● U.V.L.O. with Hysteresis
?● Operating Frequency Up to 500KHz
?● Internal Trimmed Bandgap Reference
?● High Current Totem Pole Output
?● Error Amplifier With Low Output Resistance
?● Available in 8-Pin Plastic DIP and Surface Mount 14-Pin S.O.I.C.
?● Identical pin assignment to earlier UC384X series.
