This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

A single synchronous buck-boost DC/DC converter can deliver high power due to its synchronous switching topology, but eventually the switching and/or conduction losses at higher power can overwhelm a ...

The AP65355 and AP65455 adaptive, constant on-time (COT) mode synchronous buck converters introduced by Diodes Incorporated provide low-voltage regulation with high efficiency, excellent transient ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. June 25, 2013 2 min ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

Diodes has announced four automotive buck converters for 48V rail point-of-load use. The parts are similar, but rated at 5 to 100V or 5 to 80Vin, and 2.5A or 3.5A out. There are not synchronous ...
