Key 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.
