Pin Descriptions
PIN NO. DESIGNATOR FUNCTION FUNCTION DESCRIPTION
1 3VG 3.3V FET Gate Output Drives the gate of the 3.3V MOSFET. Connect to the gate of the external N-Channel
MOSFET. At turn-on the FET gate capacitance will be charged to 12VIN voltage by a 10A
current source. An optional capacitor from this node to ground will adjust the turn-on ramp.
2, 4 12VI 12V Input +12V IC bias supply and power supply rail input to internal power switch.
3, 14 GND IC Ground Reference Connect to common of power supplies.
5 PGOOD Power Good An open drain logic output that is released to indicate all positive voltage outputs are above
minimum PCI spec. Connect to V(I/O) through resistor.
6 CRTIM Current Regulation
Duration Input
An external capacitor from this pin to ground sets the current regulation duration before
latch off. This output will pull low after the current regulation duration has expired. CR
duration = 150K x CTIM. This pin sources 20µA and has a threshold trip voltage of 2.83V.
7 FLTN Fault Indication A fault-not open drain output. Latches low once current regulation time has expired. Reset
by 12VIN POR condition or enable input signaled low. Connect to V(I/O) through resistor.
8 5VISEN 5V Current Sense Connect to the load side of the current sense resistor in series with source of external 5V
MOSFET. Monitors voltage to load.
9 5VS 5V Source Connect to source of 5V MOSFET switch. This connection along with 5VISEN senses the
voltage drop across the sense resistor.
10 EN Enable Input Controls all four internal and external switches, initiates turn-on/off
11 5VG 5V FET Gate Output Drives the gate of the 5V MOSFET. Connect to the gate of the external N-Channel
MOSFET. At turn-on the FET gate capacitance will be charged to 12VIN voltage by a 10A
current source. An optional capacitor from this node to ground will adjust the turn-on ramp
12, 13 12VO Switched 12V Output Switched 12V output.
15 M12VG Gate of Internal NMOS Connect a 5nF capacitor between M12VG and ground to stabilize the start-up ramp for the
M12V supply. This capacitor is charged with 25A during start-up.
16 M12VI -12V Input -12V Supply Input. Also provides power to the -12V current regulation circuitry.
17 M12VO Switched -12V Output Switched -12V Output.
18 CRSET Current Regulation Set Program current regulation levels for all four switches by connecting a resistor to GND. This
pin sources 100µA. See Table 1 for CR level setting formulae.
19 3VISEN 3.3V Current Sense Connect to the load side of the current sense resistor in series with source of external 3.3V
MOSFET. Monitors voltage to load.
20 3VS 3.3V Source Connect to source of 3.3V MOSFET. This connection along with 3VISEN senses the voltage
drop across the sense resistor.
