amplifier.
Switching frequency select input. Connect this pin to V
IN
for 1.28MHz operation and
AGND for 660kHz operation.
Boost converter and GPM power input.
Boost power switch input. Switch connected between SW pin and PGND pin.
Shutdown pin. Active low, pulling this pin low will disable the LM3311.
Boost output voltage feedback input.
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.
Connect capacitor from this pin to AGND.
Connect a resistor between RE and PGND.
GPM power supply input. VGH range is 5V to 30V.
Die Attach Pad. Internally connected to GND. Connect AGND and PGND pins directly to
this pad beneath the device.
