The CS3844/45 provides all the neces- sary features to implement off-line fixed frequency current-mode control with a minimum number of external components.
The CS3844 family incorporates a new precision temperature-controlled oscil- lator to minimize variations in fre- quency. An internal toggle flip-flop, which blanks the output every other clock cycle, limits the duty-cycle range to less than 50%. An undervoltage lockout ensures that V REF is stabilized before the output stage is enabled. In the CS2844/CS3844 turn on occurs at 16V and turn off at 10V. In the CS2845/CS3845 turn on is at 8.4V and turn off at 7.6V
