CS2841B
Automotive Current Mode
PWM Control Circuit
The CS2841B provides all the necessary features to implement
offline fixed frequency currentmode 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.
The CS2841B incorporates a precision temperaturecontrolled
oscillator with an internally trimmed discharge current to minimize
variations in frequency. Dutycycles 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.
