PIN DESCRIPTIONS
PIN
NAME
DESCRIPTION
1, 2
SW3
Switch Node for REG3.
3
GP3
Power Ground for REG3. Connect GP14, GP2, GP3, and GA together at a single
point as close to the IC as possible.
4
OUT10
REG10 output. Bypass it to ground with a 2.2µF capacitor.
5
OUT11
REG11 output. Bypass it to ground with a 2.2µF capacitor.
6
INL3
Power input for REG10, REG11 and REG12.
7
OUT12
REG12 output. Bypass it to ground with a 2.2µF capacitor.
8
VSELR2
Output Voltage Selection for REG2. Drive to logic low to select default output voltage.
Drive to logic high to select secondary output voltage.
9
nPBSTAT
Active-Low Open-Drain Push-Button Status Output. nPBSTAT is asserted low
whenever the nPBIN is pushed, and is high-Z otherwise.
10
GP2
Power ground for REG2. Connect GP14, GP2, GP3, and GA together at a single
point as close to the IC as possible.
11, 12
SW2
Switch Node for REG2.
13, 14
VP2
Power input for REG2. Bypass to GP2 with a high quality ceramic capacitor placed as
close to the IC as possible.
15
OUT2
Output Voltage Sense for REG2.
16
PWREN
Power Enable Input for REG3. PWREN is functional only when PWRHLD is driven
high. Drive PWREN to a logic high to turn on the REG3. Drive PWREN to a logic low
to turn off the REG3.
17
REFBP
Reference Bypass. Connect a 0.047μF ceramic capacitor from REFBP to GA. This
pin is discharged to GA in shutdown.
18
INL2
Power Input for REG8, REG9.
19
OUT9
REG9 output. Bypass it to ground with a 2.2µF capacitor.
20
GA
Analog Ground.
21
OUT4
Output voltage sense for REG4.
22
OUT8
REG8 output. Bypass it to ground with a 2.2µF capacitor.
23
SDA
Data Input for I2C Serial Interface. Data is read on the rising edge of SCL.
24
SCL
Clock Input for I2C Serial Interface.
25
VP4
Power input for REG4. Bypass to GP14 with a high quality ceramic capacitor placed
as close to the IC as possible.
