WebIn buck converters, this circuit is used when the high- side switch is the N-ch MOSFET. 1. Role of the bootstrap circuit in the buck converter The configuration of the circuit in … The efficiency of buck converters can be very high, often over 90%, making them useful for tasks such as converting a computer's main supply voltage, which is usually 12 V, down to lower voltages needed by USB, DRAM and the CPU, which are usually 5, 3.3 or 1.8 V. See more A buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply. Switching … See more There are two main phenomena impacting the efficiency: conduction losses and switching losses.
