摘要: In a switching regulator, low voltage malfunction prevention circuit controls operations of PWM comparator and output buffer circuit, such that when power source is lower than predetermined value, transistor forcibly turned off, the greater or equal to on/off in accordance with pulse signals from comparator. Furthermore, generates second reference first rises quickly rise voltage. The state inside an IC detected by comparing
