ISL6232
PGOOD
Open drain output. Active high after soft-start cycle delay
when both outputs are above 90% of the regulated voltage;
Pull low immediately when either output is below 90% of the
regulated output.
GND
Analog ground.
VIN
This pin is the input of the internal 5V and 3.3V LDO
regulators. Connect VIN to the battery or AC-adapter output.
LDO5
5V internal LDO output. LDO5 is the gate driver supply for
the external MOSFETs. It can provide a total of 100mA,
including MOSFET gate drive requirements and external
loads. If OUT5 is greater than the LDO5 switch-over
threshold, the LDO5 regulator shuts down and LDO5 pin
connects to OUT5 through a 2 Ω switch. Bypass a 4.7μF
ceramic capacitor to ground.
VCC
VCC is derived from LDO5. This pin is used to power the
internal analog integrated circuit only. The only connection to
this pin is a 0.1μF ceramic capacitor to ground.
EN3
3.3V output enable input. Connect to high for enabling 3.3V
output. Connect to low for disabling 3.3V output. When it is
connected to REF, the 3.3V output starts after 5V output
reaches regulation. Drive EN3 below the clear fault level to
reset the fault latches.
EN5
5V output enable input. Connect to high for enabling 5V
output. Connect to low for disabling to 5V output. When it is
connected to REF, the 5V output starts after 3.3V output
reaches regulation. Drive EN5 below the clear fault level to
reset the fault latches.
11
PHASE3, PHASE5
Phase connection pins for OUT3 and OUT5, respectively.
Connect to joint points of the high side MOSFET source,
output inductor, and low side MOSFET drain.
OUT5
Connect to the 5V output. It is used to sense the output
voltage and connect to the negative terminal of the sensing
resistor. If OUT5 is greater than the LDO5 switchover
threshold, the LDO5 internal linear regulator shuts down and
LDO5 connects to OUT5 through a 2 Ω switch.
OUT3
Connect to the 3.3V output. It is used to sense the output
voltage and connected to the negative terminal of the
sensing resistor. If OUT3 is greater than the LDO3
switchover threshold, the LDO3 internal linear regulator
shuts down and LDO3 connects to OUT3 through a 2.5 Ω
switch.
PGND
Power ground.
SHDN#
Shut down control input. Connect to ground, for shutting
down all internal circuitry. Connect to VIN for automatic
start-up.
SKIP#
Mode selection input. Connect to ground for pulse skip
operation. Connect to VCC for forced PWM operation.
Connect to REF for ultrasonic pulse skipping operation. For
debugging purposes, SKIP# can be pulled 1V above VCC to
disable the latch-off features of overcurrent, undervoltage,
and overvoltage protections.
REF
Reference output. Bypass a 0.22μF ceramic capacitor to
ground. REF can source up to 100μA for external loads.
COMP3, COMP5
External loop compensation for OUT3 and OUT5,
respectively. Connect a resistor in series with a capacitor to
ground.
