NAME
FUNCTION
MAX1566 (AUX2 is configured as a boost): FB2 feedback threshold is
1.25V.
MAX1567 (AUX2 is configured as an inverter): FB2 feedback threshold is
0V.
MAX1566 (AUX2 is configured as a boost): connect INDL2 to PVSU for
optimum N-channel gate drive.
MAX1567 (AUX2 is configured as an inverter): connect INDL2 to the
external P-channel MOSFET source to ensure the P channel is completely
off when DL2 swings high.
Analog Ground. Connect to all PG_ pins as close to the IC as possible.
The MAX1566 configures DL2 to drive an N-channel FET in a boost
configuration. DL2 is driven low in shutdown, overload, and thermal limit.
Drive Output. DL2
drives between INDL2
and GND.
DL2 is driven high in shutdown, overload, and thermal limit.
AUX3 Controller Gate-Drive Output. Connect to the gate of an N-channel MOSFET. DL3 drives
between GND and PVSU and supplies up to 500mA. This pin is actively driven to GND in shutdown,
overload, and thermal limit.
AUX1 Controller Gate-Drive Output. Connect to the gate of an N-channel MOSFET. DL1 drives
between GND and PVSU and supplies up to 500mA. This pin is actively driven to GND in shutdown,
overload, and thermal limit.
IC Power Input. Connect PVSU and PV together.
AUX3 Controller Compensation Node. Connect a series resistor-capacitor from this pin to GND for
compensating the converter control loop. This pin is actively driven to GND in shutdown, overload,
and thermal limit. See the
AUX Compensation
section.

FB3L
AUX3 Controller Current-Feedback Input. Connect a resistor from FB3L to GND to set LED current in
LED boost-drive circuits. The feedback threshold is 0.2V. Connect this pin to GND if using only the
FB3H feedback. This pin is high impedance in shutdown.
AUX3 Controller On/Off Input. Logic high = on; however, turn-on is locked out until 1024 OSC cycles
after the step-up has reached regulation. This pin has an internal 330k
pulldown resistance to GND.
Exposed Metal Pad. This pad is connected to ground. Note this internal connection is a soft-connect,
meaning there is no internal metal or bond wire physically connecting the exposed pad to the GND
pin. The connection is through the silicon substrate of the die and then through a conductive epoxy.
Connecting the exposed pad to ground does not remove the requirement for a good ground
connection to the appropriate pins.
