CS52843
Current Mode PWM Control Circuit
Description
The CS52843 provides all the necessary features 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
