Pin Functions

PIN(1) I/O DESCRIPTION
NAME NO.
SW 1,2,3 O Switch node, which is connected to the internal MOSFET switches. Connect inductor between SW and output capacitor.
PG 4 O Output power good (High = VOUT ready, Low = VOUT below nominal regulation) ; open drain (requires pull-up resistor)
FB 5 I Voltage feedback of adjustable version. Connect resistive voltage divider to this pin. It is recommended to connect FB to AGND on fixed output voltage versions for improved thermal performance.
AGND 6 Analog Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane.
FSW 7 I Switching Frequency Select (Low=2.5MHz, High=1.25MHz for typical operation)(2)
DEF 8 I Output Voltage Scaling (Low = nominal, High = nominal + 5%)(2)
SS/TR 9 I Soft-Start / Tracking Pin. An external capacitor connected to this pin sets the internal voltage reference rise time. It can be used for tracking and sequencing.
AVIN 10 I Supply voltage for control circuitry. Connect to same source as PVIN.
PVIN 11,12 I Supply voltage for power stage. Connect to same source as AVIN.
EN 13 I Enable input (High = enabled, Low = disabled)(2)
VOS 14 I Output voltage sense pin and connection for the control loop circuitry.
PGND 15,16 Power Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane.
Exposed Thermal Pad Must be connected to AGND (pin 6), PGND (pin 15,16) and common ground plane(3). Must be soldered to achieve appropriate power dissipation and mechanical reliability.
For more information about connecting pins, see Detailed Description and Application and Implementation sections.
An internal pull-down resistor keeps logic level low, if pin is floating.
