Pin Functions

PIN(1) I/O DESCRIPTION
NAME NUMBER
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 Must be connected to AGND. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
