Pin Functions

PIN(1) DESCRIPTION
NAME NUMBER
AGND C4 Analog Ground. Connect on PCB directly with PGND.
EN E4 Enable input (High = enabled, Low = disabled)
FB B4 Output voltage feedback. Connect resistive voltage divider to this pin and AGND. On TPS62182, connect to AGND.
PG F4 Output power good (High = VOUT ready, Low = VOUT below nominal regulation); open drain (requires pull-up resistor)
PGND A3, B3, C3, D3, E3, F3 Common power ground.
SS/TR D4 Soft-Start and Tracking Pin. An external capacitor connected to this pin sets the internal voltage reference rise time.
SW1 A2, B2, C2 Switch node for Phase 1 (master), connected to the internal MOSFET switches. Connect inductor 1 between SW1 and output capacitor.
SW2 D2, E2, F2 Switch node for Phase 2 (follower), connected to the internal MOSFET switches. Connect inductor 2 between SW2 and output capacitor.
VIN1 A1, B1, C1 Supply voltage for Phase 1.
VIN2 D1, E1, F1 Supply voltage for Phase 2.
VO A4 Output Voltage Connection
