Loop Compensation
The loop is compensated using a feedback network
around the error amplifier. Figure 25 shows a complete
Type-3 compensation network. For Type-2
compensation, eliminate R3 and C3.
Recommended PCB Layout
Good PCB layout and careful attention to temperature
rise is essential for reliable operation of the regulator.
Four-layer PCB with two-ounce copper on the top and
bottom sides and thermal vias connecting the layers are
recommended. Keep power traces wide and short to
minimize losses and ringing. Do not connect AGND to
PGND below the IC. Connect the AGND pin to PGND at
the output OR to the PGND plane.
Figure 25. Compensation Network
Since the FAN2106 employs a summing current-mode
architecture, Type-2 compensation can be used for

many applications. For applications that require wide
loop bandwidth and/or use very low-ESR output
capacitors, Type-3 compensation may be required.
R RAMP also provides feedforward compensation for
changes in V IN . With a fixed R RAMP value, the modulator
gain increases as V IN is reduced; this could make it
difficult to compensate the loop. For low-input-voltage-
range designs (3 V to 8 V), R RAMP and the compensation
component values are different compared to designs
with V IN between 8 V and 24 V.
Application note AN-8022 (TinyCalc?) can be used to
calculate the compensation components.
