Pin#
Pin Name
Description
1
Rt
Connecting a resistor from this pin to ground sets the switching frequency
(see figure 16 on page 17 for selecting resistor value)
2
VSEN2
Sense pin for OVP2 and Power Good2, Channel 2
3
Fb2
Inverting input to the error amplifier2
4
Comp2
Compensation pin for the error amplifier2
5
SS2/SD2/Mode
Soft start for channel 2, can be used as SD pin. Float this pin for current
share single output application
6
OCSet2
Current limit set point for channel2
7, 17
VcH2, VcH1
Supply voltage for the high side output drivers. These are connected to
voltage that must be typically 6V higher than their bus voltages. A 0.1uF
high frequency capacitor must be connected from these pins to PGND to
provide peak drive current capability
8,16
HDrv2, HDrv1
Output drivers for the high side power MOSFETs
9
Enable
Enable pin, recycling this pin will reset OV, SS and Prebias latch
10, 14
PGnd2, PGnd1
These pins serve as the separate grounds for MOSFET drivers and should
be connected to the system’s ground plane
11, 13
LDrv2 , LDrv1
Output drivers for the synchronous power MOSFETs
12
VcL
Supply voltage for the low side output drivers
15
Seq
Enable pin for tracking and sequencing. If this pin is not used
connect it to Vout3
18
OCSet1
Current limit set point for Channel 1
19
SS1/SD1
Soft start for Channel 1, can be used as SD pin
20
Comp1
Compensation pin for the error amplifier1
21
Fb1
Inverting input to the error amplifier1
22
VSEN1
Sense pin for OVP1 and Power Good1, Channel 1
23
Sync
External synchronization pin
24
PGood2
Power Good pin output for channel 2, open collector. This pin needs to be
externally pulled high
25
VP1
Non inverting input of error amplifier1
26
VP2
Non inverting input of error amplifier2
27
VREF
Reference Voltage
28
Gnd
IC’s Ground
29
PGood1
Power Good pin output for Channel 1, open collector. This pin needs to be
externally pulled high
30
Vcc
Supply voltage for the internal blocks of the IC. A 0.1uF high frequency
capacitor must be connected from this pin to Gnd.
31
Vout3
Output of the internal regulator. A 0.1uF high frequency capacitor must be
connected from this pin to PGnd.
32
Track
Sets the type of power up / down sequencing (ratiometric or
simultaneous). If this pin is not used connect it to Vout3
