Pin Functions

PIN(1) I/O DESCRIPTION
NAME NO.
PGND 1 — Power ground
VIN 2 I Supply voltage
EN 3 I Enable input (High = enabled, Low = disabled)
AGND 4 — Analog ground
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.
VOS 6 I Output voltage sense pin and connection for the control loop circuitry.
SW 7 O Switch node, which is connected to the internal MOSFET switches. Connect inductor between SW and output capacitor.
PG 8 O Output power good (High = VOUT ready, Low = VOUT below nominal regulation); open drain (requires pull-up resistor; goes high impedance, when device is switched off)
Exposed Thermal Pad(2) — Must be connected to AGND. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
(1) For more information about connecting pins, see Detailed Description and Application Information sections.
(2) The exposed thermal pad is available with the DSG package only, not with DGK package.
