Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
AGND 7 GND Analog ground.
AVIN 16 PWR Supply voltage for the device.
CT 6 I/O A capacitor connected between this pin and ground sets the transition time for VNEG when programmed to a new value.
CTRL 9 I Boost converter 1 (VPOS) inverting buck-boost converter (VNEG) enable/program.
EN 8 I Boost converter 2 (AVDD) enable.
FBS 4 I Boost converter 1 (VPOS) sense input.
OUTN 10 O Inverting buck-boost converter output (VNEG).
OUTP 3 O Boost converter 1 output (VPOS).
OUTP2 13 O Boost converter 2 output (AVDD).
PGND1 2 GND Boost converter 1 power ground.
PGND2 14 GND Boost converter 2 power ground.
PVIN 12 PWR Inverting buck-boost converter power stage supply voltage.
SELP2 5 I Boost converter 2 output voltage selection pin. AVDD = 7.7 V when SELP2 = low and 5.8 V when SELP2 = high.
SWN 11 I/O Inverting buck-boost converter switch pin.
SWP1 1 I Boost converter 1 switch pin.
SWP2 15 I Boost converter 2 switch pin.
Exposed thermal pad — Connect this pad to AGND, PGND1 and PGND2.
(1) GND = Ground, PWR = Power, I = Input, O = Output, I/O = Input/Output
