CS2842A/3843A SERIES CS2842A/CS3842A CS2843A/CS3843A Off-Line Current Mode PWM Control Circuit with Undervoltage Lockout Description 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 dutycycle clamp eliminates the need for an external oscillator when a 50% dutycycle is used.
Duty-cycles greater than 50% are also possible.
On board logic ensures that VREF is stabilized before the output stage is enabled.
