Steps up a lower input voltage to a higher output voltage.
D=TonT×100%cap D equals the fraction with numerator cap T sub o n end-sub and denominator cap T end-fraction cross 100 % Pulse Width Modulated DC-DC Converters
Steps down a higher input voltage to a lower output voltage. Steps up a lower input voltage to a higher output voltage
A higher duty cycle increases the average output voltage; a lower duty cycle decreases it. Pulse Width Modulated DC-DC Converters
Can either step up or step down the voltage, though it often produces an inverted (negative) output voltage relative to the input. Key Advantages
