CS2841B
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 CS2843A) is designed specifically
for use in automotive operation. The low start threshold voltage of 8.0 V
(typ), and the ability to survive 40 V automotive load dump transients
are important for automotive subsystem designs. The CS2841 series
has a history of quality and reliability in automotive applications.

PDIP-8
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 V REF is stabilized before the

output stage is enabled. Ion implant resistors provide tighter control of
undervoltage lockout.
