www.DataSheet4U.com 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 components. 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 implant resistors provide tighter control of undervoltage lockout.
