.. CS2842A, CS3842A, CS2843A, CS3843A Off- Line Current Mode PWM Control Circuit with Undervoltage Lockout The CS284XA, CS384XA provides all the necessary Features to implement off- line fixed frequency current- mode control with a minimum number of external ponents. The CS384XA family incorporates a new precision temperature- controlled oscillator with an internally trimmed discharge current to minimize variations in frequency. A precision duty- cycle clamp eliminates the need for an external oscillator when a 50% duty- cycle is used. Duty- cycles greater than 50% are also possible. On board logic ensures that VREF is stabilized before the output stage is enabled. Ion...
