Text: The UC3842/UC3843/UC3844/UC3845 are fixed frequencycurrent-mode PWM controller. They are specially , ) (VCC=15V, RT=10k, CT=3.3nF, TA= 0°C to +70°C, unless otherwise specified) Parameter PWM SECTION Max , output driver is biased to a high impedance state. Pin 6 should be shunted to ground with a bleeder , diode drops above ground. Either method causes the output of the PWM comparator to be high (refer to block diagram). The PWM latch is reset dominant so that the output will remain low until the next clock
