Automotive Current Mode PWM Control Circuit

The CS2841B provides all the necessary features to implement off-line fixed frequency current-mode control with a minimum number of external components. The CS2841B (a variation of the CS-2843A) is designed specifically for use in automotive operation. The low start threshold voltage of 8.0V (typ), and the ability to survive 40V automotive load dump transients are important for automotive subsystem designs. The CS-2841 series has a history of quality and reliability in automotive applications. The CS2841B incorporates a precision temperature-controlled Oscillator with an internally trimmed discharge current to minimize variations in frequency. 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 under-voltage lockout.
