Description	Current Mode PWM Control Circuit
Datasheet	CS52843_CherrySemiconductorCorporation.pdf

The CS52843 provides all the necessary

to implement offline fixed frequency current-mode control with a minimum number of external components. The CS52843 incorporates a new precision temperature-controlled oscillator to minimize variations in frequency. An undervoltage lockout ensures that VREF is stabilized before the output stage is enabled. In the CS52843 turn on is at 8.4V and turn off at 7.6V. Other features include low start-up current, pulse-by-pulse current limiting, and a high-current totem pole output for driving capacitiv.
