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 oscillator to minimize variations in frequency. 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 VREF is stabilized before the output stage is enabled. In the CS2844/CS3844.
