65 nm CMOS switching discontinuous-conduction mode buck converter with 330 ns start-up time for light-load power-cycled applications.

Aggressive power cycling of DC-DC converters is becoming important in many applications ranging from sensor interfaces to wireless transceivers, where the system needs to be on for only short time intervals. In this study, a switching DC-DC converter in a discontinuous-conduction mode is proposed. The DC-DC converter is well-suited for light-load applications and features a very short start-up tim...
