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 ...

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 ...

According to the datasheet of the MP3120 1: “The MP3120 is a high efficiency synchronous, current mode step-up converter. The device can boost a single-cell or two-cell AA battery up to 5V. The MP3120 ...

Second mode: Boost A-B The second 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 buck-boost converter steps a voltage up or down, producing a voltage equal to, or higher or lower than, the input voltage. A buck-boost could be used to provide a 12-V output from a 12-V battery.

This paper presents a high-efficiency positive buck- boost converter with mode-select circuits and feed-forward techniques. Four power transistors produce more conduction and more switching losses ...

A conventional two-switch buck-boost (TSBB) converter can operate in buck, boost, and buck-boost modes. This paper introduces a new topology for a two-switch buck-boost converter with the same ...

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 ...

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 ...
