Boost Status Output OVL For supervision of the Boost output voltage an open drain DMOS output is used. The output is high impedance in normal operation and low during the warning. The OVL goes LOW if the PWM comparator ...
Page 14
External loop compensation is required for converter stability, and is formed by connecting a compensation resistor-capacitor series-network ( In the case of overload or short-circuit at the DMOS output transistor is switched off by the overcurrent comparator immediately. The pulse ...
