Using a resistor of approx. 1 Ω in series with CI, the LC circuit of input inductivity and input capacitance can be damped. To stabilize the regulation circuits of the stand-by and main regulator, output capacitors CQ1 and CQ2 are necessary. Stability is guaranteed at values, CQ1 ≥ 10 µF (ESR ≤ 2 Ω) and CQ2 ≥ 10 µF (ESR ≤ 3 Ω) within the operating temperature range. 5.2.2 Enable Using the enable feature output 2 (5 V output) can be switched ON or OFF. The enable input can be connected directly to terminal 30 (battery line) or 15 (ignition line). It is also possible to control the output 2 via the microcontroller. 5.3 Further application information For further information you may contact https://www.infineon.com.
