GENERAL DESCRIPTION
The CM3842/43 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 totem pole output which is suitable for driving MOSFETs.
FEATURES
◆ Low Start-Up current ( typ. 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 8-Pin S.O.I.C.
APPLICATIONS
◆ Off-line flyback or forward converters.
◆ DC-to-DC buck or boost converter.
◆ Monitor Power Supply]
