Description	Current Mode PWM Control Circuit with 50% Max Duty Cycle
Datasheet	CS52845_CherrySemiconductorCorporation.pdf

The CS52845 provides all the necessary

to implement offline fixed frequency current-mode control with a minimum number of external components. The CS52845 incorporates a new precision temperature-controlled oscillator to minimize variations in frequency. An internal toggle flipflop, 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 CS52845 turn on is at 8.4V and turn off at 7.6V. Other featur.
