Pin Functions

PIN(1) I/O DESCRIPTION
NAME NO.
AGND 6 — Analog Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane.
AVIN 10 I Supply voltage for control circuitry. Connect to same source as PVIN.
DEF 8 I Output Voltage Scaling (Low = nominal, High = nominal + 5%)(3)
EN 13 I Enable input (High = enabled, Low = disabled)(3)
FB 5 I Voltage feedback. Connect resistive voltage divider to this pin.
FSW 7 I Switching Frequency Select (Low ≈ 2.5 MHz, High ≈ 1.25 MHz(2) for typical operation)(3)
PG 4 O Output power good (High = VOUT ready, Low = VOUT below nominal regulation) ; open drain (requires pull-up resistor)
PGND 15, 16 — Power ground. Must be connected directly to the Exposed Thermal Pad and common ground plane.
PVIN 11, 12 I Supply voltage for power stage. Connect to same source as AVIN.
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.
SW 1, 2, 3 O Switch node, which is connected to the internal MOSFET switches. Connect inductor between SW and output capacitor.
VOS 14 I Output voltage sense pin and connection for the control loop circuitry.
Exposed Thermal Pad — — Must be connected to AGND (pin 6), PGND (pin 15,16) and common ground plane. See Layout Example. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
(1) For more information about connecting pins, see Detailed Description and Application and Implementation sections.
(2) Connect FSW to VOUT or PG in this case.
(3) An internal pull-down resistor keeps logic level low, if pin is floating.
