High Performance Current Mode Controllers The UC3842A, UC3843A series of high performance fixed. dimensions section on page 15 38c42 of this data sheet. 38c42 datasheet. High Performance Current Mode Controllers 38c42 The UC3842B, UC3843B series are high performance fixed. In the UCCx8C41 , UCCx8C44, UCCx8C45 the frequency of OUT is one- half that of the oscillator due to an internal T flipflop. This limits the maximum duty cycle to < 50%. An 38c42 IMPORTANT NOTICE at the end of this data sheet addresses availability intellectual property datasheet matters , use in safety- critical applications, warranty, changes other important disclaimers.

The OUT pin in the UCCx8C40 UCCx8C42, , UCCx8C43 is the same frequency as the oscillator, 38c42 can operate near 100% duty cycle. 38C42 datasheet Datasheet free, 38C42 PDF, datenblatt, Datasheets, 38C42 manual, 38C42, 38C42 pdf, Electronics 38C42, 38C42 Data sheet, datasheet, alldatasheet data sheet.
The MIC38C4x are ﬁxed frequency, high performance, cur- rent- mode PWM controllers. Micrel’ s BiCMOS devices are pin compatible with 384x bipolar devices but feature several improvements. Undervoltage lockout circuitry allows the ’ 42 and ’ 44 versions to start up at 14. 5V and operate down to 9V, and the ’ 43 and.
