p is defined by Equation 20 on page 36, gCS represents the current sense
transconductance (see Table 5: Electrical characteristics on page 8) and gm TYP the error
amplifier transconductance.
Equation 36
Example 2
Considering VIN = 12 V, VOUT = 3.3 V, L = 6.8 H, COUT = 15 F, fSW = 500 kHz.
The maximum system bandwidth is 80 kHz. Assuming to design the compensation network
to achieve a system bandwidth of 70 kHz:
Equation 37
Equation 38
