In order to achieve this he switched from a linear regulator to a buck-boost converter. ... He’s just now finishing up the Arduino IDE support for the board, which is pretty cool.

Compared with the current means of utilizing a bypass boost converter followed by an LDO, the Max77827 improves efficiency by up to 12%, the manufacturer claims. Compared with utilizing a buck ...

TDK-Lambda has introduced a series of rugged non-isolated 300W buck-boost dc-dc converters. The RGC series has a 9 to 53V imput range and adjustable output voltages of 9.6 to 48V (8Amax), or 5 to 28V ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage ...

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 ...

In this case, a synchronous 4-switch buck-boost converter using a single inductor offers the same advantages as a 2-switch synchronous buck or boost. The LT8705 is a synchronous 4-switch buck-boost ...

Figure 1. 15–58V IN to 33.3V 3A LED Driver with Up to 98.5% Efficiency. The 4-switch synchronous topology drives high power LEDs with minimal switch power loss (and minimal temperature rise). Unlike ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

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 ...
