On the basis of a buck–boost circuit, coupling inductance has been proposed by Ali et al. (2021) to regulate power output, forming a secondary voltage gain adjustment strategy.

Inverting buck-boost circuits are commonly used to generate negative supply voltages from positive voltages. However, additional level-shifting circuits may be necessary if the power supply is ...

The magnitude of the negative voltage generated by inverting buck-boost circuits can be higher or lower than that of the available positive voltage. For example, –8 V or even –14 V can be ...

Due to wide application of switched capacitor network in power electronic circuits, Buck-Boost converter with switched capacitor network could get a better voltagedrop effect with the same duty ratio ...

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 ...

Electric schematic Figure 1 shows the simple but fully functional electrical diagram. The symmetrical configuration allows operating in four different modes, which are selectable by the user. It ...

Highly integrated buck regulator ICs with internal compensation makes these approaches easy to use and attractive for power supply design. The Table 2 pros and cons of using the buck method and ...

This reference design is for a buck-boost LED driver. The MAX16834 current-mode high-brightness LED driver is featured, and the MAX16834 EV (evaluation) kit is used to implement the design. The ...

This application note presents the design equations, schematics and source code for a 5.5W power LED driver using the PIC16F785 MCU. The application, as shown, can be connected to operate as a ...

Electronic circuits typically operate from regulated positive output voltages, often provided by buck regulators. If a negative output voltage is also required, the same buck controller often can be ...
