WebJul 21, 2006 · A switch-mode power supply (SMPS) provides a more efficient solution for driving a high power LED. An SMPS supply can buck or boost the input voltage to the correct level to provide the desired LED current. The system input voltage range and the required LED for-ward voltage will determine the SMPS topology that is selected. WebNov 27, 2024 · A push-pull converter opens up lots of conversion possibilities, such as Buck, Boost, Buck-Boost, isolated, or even non-isolated topologies, also it is one of the oldest switching topologies used in power electronics that require minimum components to produce medium power outputs (Typically - 150W to 500W) with multiple output voltage.

Buck convertors typically operate with a switching frequency range from 100 kHz to a few MHz. A higher switching frequency allows for use of smaller inductors and capacitors, but also increases lost efficiency to more frequent transistor switching. See more A buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply. Switching … See more There are two main phenomena impacting the efficiency: conduction losses and switching losses.
