Application information
A step-up (or boost) converter is a switching DC-DC converter able to generate an output
voltage higher than (or at least equal to) the input voltage.
Figure 5.
The switching element (Sw) is typically driven by a fixed frequency squared waveform
generated by a PWM controller.
When Sw is closed (T
depending on the voltage across the inductor and its inductance value. During this time the
output voltage is sustained by C
output to input stages.
When Sw is open (T
voltage on node “A” is higher than output voltage. During this phase the current in the
inductor decreases while the output voltage increases.
Following figure shows the behavior of the current on the inductor.
