Abstract
An apparatus and method for a boost power converter with improved electrical overstress (EOS) tolerance is disclosed. A boost power converter provides a providing a pulse width modulation (PWM) boost power converter with an electrical overstress (EOS) boost over-voltage comparator/switch network comprises a boost power converter, a boost overvoltage comparator, a boost overvoltage comparator feedback network, and a boost overvoltage switch. The methodology for the boost converter with improved electrical overstress (EOS) tolerance defines an absolute maximum voltage condition, provides a voltage limit below the defined absolute maximum voltage condition, and initiates turn-on of the boost overvoltage switch according to the voltage limit.
