Auxiliary Controller 3 Compensation Node. Connect a series resistor-capacitor from COMP3 to GND to
compensate the control loop. COMP3 is actively driven to GND in shutdown and thermal limit.
Auxiliary Controller 3 Feedback Input. Connect a resistive voltage-divider from the output voltage to FB3 to
GND. The FB3 feedback threshold is 1.25V. This pin is high impedance in shutdown.
Step-Up Converter Output. OUTSUB powers the MAX1565 and is the sense input when FBSELSU is GND
and the output is 3.3V. Connect OUTSUA to OUTSUB.
Auxiliary Controller 3 Gate-Drive Output. Connect the gate of an N-channel MOSFET to DL3. DL3 swings
from GND to OUTSU and supplies up to 500mA. DL3 is driven to GND in shutdown and thermal limit.
Auxiliary Controller 2 Gate-Drive Output. Connect the gate of an N-channel MOSFET to DL2. DL2 swings
from GND to OUTSU and supplies up to 500mA. DL2 is driven to GND in shutdown and thermal limit.
Auxiliary Controller 1 Gate-Drive Output. Connect the gate of an N-channel MOSFET to DL1. DL1 swings
from GND to OUTSU and supplies up to 500mA. DL1 is driven to GND in shutdown and thermal limit.
Quiet Ground. Connect GND to PGND as close to the IC as possible.
Auxiliary Controller 2 Compensation Node. Connect a series resistor-capacitor from COMP2 to GND to
compensate the control loop. COMP2 is actively driven to GND in shutdown and thermal limit.
Auxiliary Controller 2 Feedback Input. Connect a resistive voltage-divider from the output voltage to FB2 to
GND to set the output voltage. The FB2 feedback threshold is 1.25V. This pin is high impedance in
shutdown.
Exposed Underside Metal Pad. This pad must be soldered to the PC board to achieve package thermal and
mechanical ratings. The exposed pad is electrically connected to GND.
