This 1.5V 555 LED driver is more of a fun learning experiment than a practical circuit. While the TLC555 can indeed drive a 3V white LED using the inductive discharge technique, it typifies the kind ...

High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits ... of LED lighting to make the best trade-off. This Design Idea describes a simpler and ...

as a few years ago Zetex – now part of Diodes – employed original 555 designer Hans Camenzind to develop an 0.9V version from scratch. This was introduced as the ZSCT1555. What is unique about Semtech ...
