A capacitor from this pin to LGnd sets the off time for the non-synchronous regulator (VI/O). 13 COMP2 VI/O section error amp output. PWM comparator inverting input. A capacitor to LGnd provides error amp compensation. 12 VOUT2 VI/O section current limit comparator inverting input. 11 VFB2 VI/O section error amp inverting feedback input. 10 VFFB2 VI/O PWM comparator fast feedback non-inverting input. VI/O sec- tion current limit comparator non-inverting input. 9 LGnd Logic ground. 7VFB1 VCORE section error amp inverting input, PWRGD and OVP compara- tor input. 6VOUT1 VCORE section current limit comparator inverting input. 5 COMP1 VCORE section error amp output. VCORE section PWM comparator inverting input. A capacitor to LGnd provides error amp compensa- tion. 4COFF1 Off-Time Capacitor Pin. A capacitor from this pin to LGnd sets the off time for the synchronous regulator (VCORE). 8VFFB1 VCORE section PWM comparator fast feedback non-inverting input. VCORE section current limit comparator non-inverting input. |
