PVIN
Power input. Input capacitor CIN must be placed as close to IC
as possible.

AVDD
Analog and I2C interface power input.
D2

SCL
I2C interface clock input.

VSEL
Nominal VOUT setting select input pin.
VSEL = Low selects {0x11.ENSEL0, 0x11.VoutSEL0[6:0],
0x14.PWM0}.
VSEL = High selects {0x10.ENSEL1, 0x10.VoutSEL1[6:0],
0x14.PWM1}.
E1

VOUT
Step-down converter output voltage sense input.
E2
3
GNDR
Remote ground sense input.
E3
1
EN
Enable control input. The IC enable control pin turns on the
step-down converter if the internal register ENSEL bit = 1. If
ENSEL = 0, EN goes high still cannot enable step-down
converter. The EN pin includes a internal pull-down current about
1
A.
When IC protection occurs and is latched in shutdown state,
toggling EN or re-power AVDD can reset the latch state.

NC
No internal connection.

12,
15 (Exposed Pad)
GND
Ground. The exposed pad must be soldered to a large PCB and
connected to GND for maximum power dissipation.
