Pin#
Name
Function
1
VSEN
Remote Buffer Output. It manages OVP and UVP protections and
PGOOD. See Section 9 for details.
2FB
Error Amplifier Inverting Input. Connect with a resistor RFB vs. VSEN and
with an RF - CF vs. COMP.
3COMP
Error Amplifier Output. Connect with an RF - CF vs. FB.
The device cannot be disabled by pulling down this pin.
4SGND
All the internal references are referred to this pin. Connect to the PCB
Signal Ground.
5VCC
Device Power Supply as well as LS driver supply.
Operative voltage is 12V ±15%. Filter with at least 1
F MLCC vs. ground.
6
N.C.
Not Internally Bonded.
7LGATE1
Channel 1 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
8
PGND
LS Driver return path. Connect to Power ground Plane.
