Combined buck & boost converter? PI Controller DC-DC Buck Converter with PIC16F877A. Advice about MC34063 based buck converter diagram. In LTspice, we can measure the ON time as 3.5us and a period of 6.14us, giving a measured duty cycle of 57%. With a boost converter, the current in the inductor must be continuous for this equation to hold true. A boost converter is used as the voltage increase mechanism in the circuit known as the 'Joule thief', which is a circuit topology used with low power battery applications, and is purposed at the ability of a boost converter to 'steal' the remaining energy in a battery. The energy remaining would To be clear, the other common use of the boost converter is for AC to DC power supplies for power factor correction and that requires a complete and separate treatment. When I say DC to DC, I mean converters with an input voltage that is positive and does not move up and down quickly.
