Wide dynamic current range switching regulator

摘要: A switching regulator is adaptable for connection to a DC power source serve as supply. self-oscillating has an output voltage feedback circuit connected thereto which interrupts the when rises above prescribed level. The current that flows through switch of sensed and it gets beyond predetermined amount, Schmidt trigger turned off. then turns off switch, permitting inductor in supply filter capacitor. When across capacitor builds up level, detects level deactivates switch.
