The advantages offered by a synchronous buck or boost topology can also be applied to a buck-boost topology, where the converter’s output voltage falls within its input range. In this case, a ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

This article presents the 2nd part of the switching regulator topologies, which will cover the buck/boost discontinuous and continuous mode. It will also describe the synchronous and asynchronous ...

Figure 3. An asynchronous buck regulator circuit. In an "asynchronous" topology switching regulator (see Fig. 3), t he energy stored in the inductor and then delivered to the load during the MOSFET’s ...

The AP68255Q/AP68355Q and AP6A255Q/AP6A355Q incorporate 500mΩ power MOSFETs to deliver high-efficiency step-down DC-DC conversion with up to 3.5A of continuous output current. These converters cover ...

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 ...
