◆ 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]
