fastest transition times and waveforms without
oscillations. Low gate charge MOSFETs will
switch faster than those with higher gate charge
specifications.
?
Lowering the current sense resistor value will
decrease the power dissipated in the resistor.
However, it will also increase the overcurrent
limit and may require larger MOSFETs and
?
For the same size inductor, a lower value will
have fewer turns and therefore, lower winding
resistance. However, using too small of a value
will increase the inductor current and therefore
require more output capacitors to filter the output
?
inductor components to handle the higher
currents.
Use low ESR output capacitors to minimize the
power dissipated in the capacitor’s ESR.
