Current overload protection circuit

摘要: A constant potential power supply with current overload protection having a series switching regulator including circuit controlled by both Schmitt-trigger an output voltage detector to maintain the load within predetermined range during normal operation and foldback characteristic which operates when goes above value. The is actuated signal from detection decreases below certain value enable conduct input source disabled as After actuation of until it disabled, charging passes into integrating capacitor. This capacitor, coupled across load, discharges through cut-off. circuit, senses current, exclusively controls enables disables increases level. particular arrangement between such that not loop thereby improving overall regulation provides significant thereto.
