PIN DESCRIPTIONS
TERMINAL
DESCRIPTION
NAME
NO.
1
Zero VDC reference for the analog control circuitry. These pins should be connected directly to the PCB
5
analog ground plane. Not all pins are connected together internally. All pins must be connected together
AGND
29
externally with a copper plane or pour directly under the module. Connect the AGND copper area to the
PGND copper area at a single point; directly at the pin 37 PowerPAD using multiple vias. See the
33
recommended layout in Figure 34.
34
This pad provides both an electrical and thermal connection to the PCB. This pad should be connected
PowerPAD
directly to the PCB power ground plane using multiple vias for good electrical and thermal performance. The
37
(PGND)
same vias should also be used to connect to the PCB analog ground plane. See the recommended layout in
2
3
Do not connect. Do not connect these pins to AGND, to another DNC pin, or to any other voltage. These
DNC
15
pins are connected to internal circuitry. Each pin must be soldered to an isolated pad.
16
26
Inhibit and UVLO adjust pin. Use an open drain or open collector output logic to control the INH function. A
INH/UVLO
28
resistor between this pin and AGND adjusts the UVLO voltage.
17
18
19
20
21
Phase switch node. These pins should be connected by a small copper island under the device for thermal
PH
relief. Do not connect any external component to this pin or tie it to a pin of another function.

25
39
PWRGD
27
Power good fault pin. Asserts low if the output voltage is out of tolerance. A pull-up resistor is required.
This pin automatically selects between RT mode and CLK mode. An external timing resistor adjusts the
RT/CLK
4
switching frequency of the device. In CLK mode, the device synchronizes to an external clock.
Remote sense connection. Connect this pin to VOUT at the load for improved regulation. This pin must be
SENSE+
36
connected to VOUT at the load, or at the module pins.
Slow-start and tracking pin. Connecting an external capacitor to this pin adjusts the output voltage rise time.
SS/TR
6
A voltage applied to this pin allows for tracking and sequencing control.
Slow-start or track feature select. Connect this pin to AGND to enable the internal SS capacitor with a SS
STSEL
7
interval of approximately 1.1 ms. Leave this pin open to enable the TR feature.
VADJ
35
Connecting a resistor between this pin and AGND sets the output voltage above the 0.8V default voltage.
30
The positive input voltage power pins, which are referenced to PGND. Connect external input capacitance
VIN
31
between these pins and the PGND plane, close to the device.
32

11
VOUT
Output voltage. Connect output capacitors between these pins and the PGND plane, close to the device.
