Efficient Power Conversion Corporation (EPC) announces the release of the EPC91109, a performance evaluation board designed to demonstrate the benefits of enhancement-mode gallium nitride (eGaN) power ...

Combining a buck-boost topology and Silent Switcher technology brings very low EMI at the highest power-conversion efficiency. In many applications, voltages require upward and downward conversion ...

This article introduces a circuit to cover such a requirement using the XLSEMI automotive/industrial graded boost/buck-boost/inverting TO263-5L XL6019 chip. Its input voltage range is 5V to 40V and ...

Buck and boost converters can operate in two distinct and autonomous setups. The first circuit aims to decrease the input voltage, whereas the second circuit aims to increase the voltage. This post ...

To address the challenge of shutting down a buck-boost converter, this design incorporates an external under-voltage lockout (UVLO) circuit to reduce the UVLO hysteresis. This LMR16020 buck-boost ...

That’s due to the best possible built-in immunity to any circuit non-idealities. Figure 2 illustrates a configurable 3/4/5-level FCML buck power converter. 2.

Fourth mode: Boost B-A The fourth mode of the circuit provides for operation as a Boost, ie as a converter whose output voltage is higher than the input voltage. The circuit is also called “step-up”.

A circuit that can create a dc voltage higher than that of a battery is referred to as a step-up dc–dc converter, and one that can create a dc voltage lower than that of a battery is known as a ...

A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China ...

This research work proposes transformerless buck-boost converter with common ground. The proposed converter consists of five switches that can be configured to either noninverting or inverting output ...

In the previous two articles of our Power Electronics Course, we examined buck and boost converters in two separate and independent configurations. The purpose of the first circuit is to reduce the ...
