Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VOUT1 1 Output Voltage Node Phase 1 (master), Must be connect with VOUT2
PGND1 2, 3, 20,21 Power Ground Phase 1 (master)
VIN1 4, 24 Supply voltage Phase 1 (master)
EN 5 Enable input (High=Enabled, Low = Disabled)
PG 6 Power Good (open drain, requires pull-up resistor)
VSEL 7 Output Voltage Select (High = VOUT2, Low=VOUT1) , VOUT1 < VOUT2
TG 8 Thermal Good (open drain, requires pull-up resistor)
MODE 9 Operating mode selection (Low=Automatic PWM/PSM, High = Forced PWM)
VIN2 10, 23 Supply voltage Phase 2
PGND2 11,12, 14, 22 Power Ground Phase 2
VOUT2 13 Output Voltage Node Phase 2, Must be connected with VOUT1
SS/TR 15 Soft-Start / Tracking. An external capacitor connected to this pin sets the output voltage rise time.
AGND 16 Analog Ground
FB 17 Output voltage feedback for the adjustable version. Connect resistive voltage divider to this pin.
RS 18 Resistor Select. Connect resistor that sets the level for the second output voltage here (activated by VSEL= High)
VO 19 VOUT detection (connect to VOUT, output discharge is internally connected to this pin)
