ッチングレギュレータの起動回路。At startup, there is a charging circuit whose potential increases when the power is turned on, and an N whose anode is connected to the charging circuit and whose anode potential is turned on for a period of time greater than the gate potential due to charging of the charging circuit.
It includes a gate thyristor and a switching element that performs a voltage stabilizing operation, and when the N-gate thyristor is turned on, the switching element is put into operation, and the charge in the charging circuit is partially discharged via the N-gate thyristor and the switching element. and a discharging circuit having a time constant sufficiently smaller than the time constant of the charging circuit, which discharges the charge of the charging circuit through the switching element without going through the N-gate thyristor after the N-gate thyristor is turned off. Switching regulator startup circuit.
