I/O DESCRIPTION
NAME NO.
PGND 1 — Power ground connection
VIN 2 I Supply voltage for the converter
EN 3 I Enable input (High = enabled, Low = disabled)
NC 4 — This pin is recommended to be connected to AGND but can left be floating
Voltage feedback of adjustable version. Connect resistive divider to this pin. TI recommends
FB 5 I
connecting FB to AGND for fixed voltage versions for improved thermal performance.
AGND 6 — Analog ground connection
PG 7 O Output power good (open drain, requires pullup resistor)
Sleep mode input (High = normal operation, Low = sleep mode operation). Can be operated
SLEEP 8 I
dynamically during operation. If sleep mode is not used, connect to VOUT.
Switch node, connected to the internal MOSFET switches. Connect inductor between SW and
SW 9 O
output capacitor.
VOS 10 I Output voltage sense pin and connection for the control loop circuitry.
Exposed Must be connected to AGND and PGND. Must be soldered to achieve appropriate power dissipation
— —
Thermal Pad and mechanical reliability.
