Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

It is rare that an integrated circuit stays on the market for 25 years. And it is surprising that, except for a CMOS derivative, the 555 timer has never been updated. It has been shrunk somewhat, but ...

This paper presents a timer circuit designed for an adaptive on-time (AOT) Buck DC-DC converter. The circuit utilizes input voltage feedforward compensation and output feedback techniques to maintain ...
