Buck converter circuit
A typical choice of external components for the buck converter is given in figure 14. For
basic operation of the buck converter the input capacitor C
I2, the bootstrap capacitor
C
BTP, the catch diode DB, the induuctance LB, the output capacitor CB and the charge
pump capacitors C
FLY and CCCP are necessary.
The additional components shown on top of the circuit lower the electromagnetic
emission (L
I, CI1, CI3, RSlew) and the switching losses (RBoost, CBoost, DBoost). For 12V
battery systems the switching loss minimization feature might not be used. In that case
the Boost pin (33) is connected directly to the IN pins (32, 30) and the components
R
Boost, CBoost and DBoost are left away
5.2.1
Buck inductance (L
B) selection:
The inductance value determines together with the input voltage, the output voltage and
the switching frequency the current ripple which occurs during normal operation of the
step down converter. This current ripple is important for the all over ripple at the output
of the switching converter.
As a rule of thumb this current ripple
I is chosen between 10% and 50% of the load
current.
For optimum operation of the control loop of the Buck converter the inductance value
should be in the range indicated in section 3.3, recommended operation range.
When picking finally the inductance of a certain supplier (Epcos, Coilcraft etc.) the
saturation current has to be considered. With a maximum current limit of the Buck
converter of 3.2A an inductance with a minimum saturation current of 3.2A has to be
chosen.
