Bootstrap Capacitor C BST
Depending on the duty cycle and gate drive current of the phase IC, a 0.1uF to 1uF capacitor is needed for the
bootstrap circuit.
Decoupling Capacitors for Phase IC
0.1uF-1uF decoupling capacitors are required at VCC and VCCL pins of phase ICs.
VOLTAGE LOOP COMPENSATION
The adaptive voltage positioning (AVP is usually used in the computer applications to improve the transient
response and reduce the power loss at heavy load. Like current mode control, the adaptive voltage positioning loop
introduces extra zero to the voltage loop and splits the double poles of the power stage, which make the voltage
loop compensation much easier.
Resistors R FB and R DRP are chosen according to Equations (15) and (16), and the selection of compensation types
depends on the capacitors used. For the applications using Electrolytic, Polymer or AL-Polymer capacitors, type II
compensation shown in Figure 18 (a) is usually enough. While for the applications with only ceramic capacitors,
type III compensation shown in Figure 18 (b) is preferred.
