Description
www.DataSheet4U.com ® UC3842T UC3843T UC3844T UC3845T HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER *....TRIMMED OSCILLATOR FOR PRECIS.
Features
* to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout featuring start-up current less than 0.5mA, a precision reference trimApplications
* The corresponding thresholds for the UC3843T and UC3845T are 8.5 V and 7.9 V. The UC3842T and UC3843T can operate to duty cycles approaching 100%. A range of zero to < 50 % is obtained by the UC3844T and UC3845T by the addition of an internal toggle flip flop which blanks the output off every otherUC3843T Distributors
