Pin
Name
Function
8
NEG
Negative input terminal of the Op-Amp.
9
POS
Positive input terminal of the Op-Amp.
10
AGND
Analog ground for the step-up regulator, LDO, and Op-Amp. Connect directly to DAP and PGND
beneath the device.
11
ADJ
LDO output voltage feedback input.
12
V
OUT
LDO regulator output.
13
LV
IN
LDO power input.
14
SS
Boost converter soft start pin.
15
V
C
Boost compensation network connection. Connected to the output of the voltage error amplifier.
16
FREQ
Switching frequency select input. Connect this pin to V
IN for 1.28MHz operation and AGND for
660kHz operation.
17
V
IN
Boost converter and GPM power input.
18
SW
Boost power switch input. Switch connected between SW pin and PGND pin.
19
SHDN
Shutdown pin. Active low, pulling this pin low will disable the LM3311.
20
FB
Boost output voltage feedback input.
21
PGND
Power Ground. Source connection of the step-up regulator NMOS switch and ground for the GPM
circuit. Connect AGND and PGND directly to the DAP beneath the device.
22
CE
Connect capacitor from this pin to AGND.
23
RE
Connect a resistor between RE and PGND.
24
VGH
GPM power supply input. VGH range is 5V to 30V.
DAP
Die Attach Pad. Internally connected to GND. Connect AGND and PGND pins directly to this pad
beneath the device.
