Boost Switching Converter Design Equations Title The boost converter is a high efficiency step-up DC/DC switching converter. The converter uses a transistor switch, typically a MOSFET, to pulse width modulate the voltage into an inductor. Rectangular pulses of voltage into an inductor result in a triangular current waveform.

This converter produces an output voltage V that is greater in magnitude than the input voltage V g. Its conversion ratio is M(D) = 1/(1 – D). In the buck-boost converter, the switch alternately connects the inductor across the power input and output voltages. This converter inverts the polarity of the voltage, and can either increase or decrease

The main power MOSFET, or control MOSFET or low side MOSFET, should be the hottest part of your converter. If it isn't, the design probably needs review. In boost converters, switching loss tends to dominate because the voltage slews back and forth from zero to V-OUT, and the current slews back and forth from zero to I-IN.
