Description
Step-down converter; converts a higher DC input voltage to a lower DC output voltage with high efficiency.
A technique for improving the efficiency of rectification by replacing diodes with actively-controlled
switches, such as transistors.
Pulse width modulation (fixed frequency).
Pulse frequency modulation (fixed pulse width).
Equivalent series resistance.
When using an N-Channel Power MOSFET transistor as a high-side switch for the converter switching
output, a gate voltage higher than the supply voltage is needed to turn the transistor fully on.
For this purpose, a charge pump circuit, called the bootstrap control, is implemented to provide this high
supply voltage for the high-side power MOSFET driver block.
