Total loop gain
In summary, the open loop gain can be expressed as:
G(s)=GDIV(s)⋅GCO(s)⋅A0(s)
(32)
example 1:
VIN = 12 V, VOUT = 3.3 V, ROUT = 1.67 Ω
Selecting the L6986H with VOUT=3.3 V, fSW = 500 kHz, L = 10 µH, COUT = 20 µF and ESR = 3 mΩ, RC = 75 kΩ,
CC = 330 pF, CP = 2.2 pF (please refer to Table 19. L6986H 3V3 demonstration board BOM), the gain and phase
bode diagrams are plotted respectively in Figure 38. Module plot and Figure 39. Phase plot.
Figure 38. Module plot
BW = 55 kHZ
phase margin = 60 °
Figure 39. Phase plot
The blue solid trace represents the transfer function including the sampling effect term (see ), the dotted blue
trace neglects the contribution.
