FUNCTION
16 Lead SO Narrow
1
GATE(H)1
High Side Switch FET driver pin for the channel 1 FET.
2
GATE(L)1
Low Side Synchronous FET driver pin for the channel 1 FET.
3
PGND1
High Current ground for the GATE(H)1 and GATE(L)1 pins.
4
LGND
Logic ground. All control circuits are referenced to this pin. IC
substrate connection.
5
SGND
Ground sense for the internal reference.
6
VFFB1
Input for the channel 1 PWM comparator.
7
VFB1
Error amplifier inverting input for channel 1.
8
COMP1
Channel 1 Error Amp output. PWM Comparator reference
input. A capacitor to LGND provides Error Amp compensa-
tion. The same capacitor provides Soft Start timing for chan-
nel 1. This pin also disables the channel 1 output when
pulled below 0.3 V.
9
COMP2
Channel 2 Error Amp output. PWM Comparator reference
input. A capacitor to LGND provides Error Amp compensa-
tion and Soft Start timing for channel 2. Channel 2 output is
disabled when this pin is pulled below 0.3 V.
