Calculating, Inductance, Current, Voltage and Duty Cycle in a Boost Converter Here we’ll discuss only the continuous mode, which is the preferable way to operate a boost converter. Let’s evaluate the calculations involved with a boost converter in continuous mode: Inductor Current Build-Up (Tr...
The TPS63036 is a non inverting buck-boost converter able to provide a regulated output voltage from an input supply that can be higher or lower than the output voltage. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectificatio...

For the boost converter, the output capacitor supplies the load current when the main switch is ON, and therefore the output voltage ripple is a function of duty cycle and load current. Use the following equation to calculate the steady state output voltage ripple: ΔVOUT = (IOUT × LIN ...
To ensure system safety and stability, the two output voltages of an IPOS converter need to be balanced. On this basis, an IPOS three-state boost converter with a balanced output voltage is proposed in this paper. At the same time, output voltage balance can be obtained by adjusting the ...
In a perfect PFC circuit, the input current is in phase with the input voltage (as it would be with a pure resistor), without any input current harmonics. This document presents the digital implementation of a CCM PFC boost converter. 1.1 Boost topology Although active PFC ca...
The MAX1605 boost converter contains a 0.5A internal switch in a tiny 6-pin SOT23 package. The IC operates from a +2.4V to +5.5V supply voltage, but can boost battery voltages as low as 0.8V up to 30V at the output. The MAX1605 uses a unique control scheme providing the highest eff...
