UC3842B HIGH-PERFORMANCE PWM CONTROLLER

UC3842B Description

UC2842B/3B/4B/5B ® UC3842B/3B/4B/5B HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER .TRIMMED OSCILLATOR FOR PRECISE FREQUENCY CONTROL .OSCILLATOR F.
The UC384xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with.

UC3842B 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 trim

UC3842B Applications

* The corresponding thresholds for the UC3843B and UC3845B are 8.5 V and 7.9 V. The UC3842B and UC3843B can operate to duty cycles approaching 100%. A range of the zero to < 50 % is obtained by the UC3844B and UC3845B by the addition of an internal toggle flip flop which blanks the output off every ot
