Description
Current Mode PWM Controller

Features

* Optimized For Off-line And DC To DC Converters Low Start Up Current (

Applications

* The corresponding thresholds for the UC1843 and UC1845 are 8.4V and 7.6V. The UC1842 and UC1843 can operate to duty cycles approaching 100%. A range of zero to 50% is obtained by the UC1844 and UC1845 by the addition of an internal toggle flip flop which blanks the output off every other clock cycl
