TERMINAL FUNCTIONS
I/O
DESCRIPTION
I
Current limit setting for Buck3. Fit a resistor from this pin to ground to set
the peak current limit on the output inductor.
I
Soft start pin for Buck3. Fit a small ceramic capacitor to this pin to set the
converter soft start time.
O
Compensation for Buck3. Fit a series RC circuit to this pin to complete
the compensation circuit of this converter.
I
Feedback pin for Buck3. Connect a divider set to 0.8 V from the output of
the converter to ground.
Unused pin, connect to ground
I
Oscillator set. This resistor sets the frequency of internal autonomous
clock.
I
Feedback pin for Buck1. Connect a divider set to 0.8 V from the output of
the converter to ground.
O
Compensation pin for Buck1. Fit a series RC circuit to this pin to complete
the compensation circuit of this converter.
I
Soft-start pin for Buck1. Fit a small ceramic capacitor to this pin to set the
converter soft-start time.
I
Current limit setting pin for Buck1. Fit a resistor from this pin to ground to
set the peak current limit on the output inductor.
Enable pin for Buck1. A high signal on this pin enables the regulator
I
Buck. For a delayed start-up add a small ceramic capacitor from this pin
to ground.
Bootstrap capacitor for Buck1. Fit a 47-nF ceramic capacitor from this pin
to the switching node.
I
Input supply for Buck1. Fit a 10-µF ceramic capacitor close to this pin.
O
Switching node for Buck1
O
Switching node for Buck2
I
Input supply for Buck2. Fit a 10-µF ceramic capacitor close to this pin.
Bootstrap capacitor for Buck2. Fit a 47-nF ceramic capacitor from this pin
to the switching node.
I
Enable pin for Buck2. A high signal on this pin enables the regulator. For
a delayed start-up add a small ceramic capacitor from this pin to ground.
I
Current limit setting pin for Buck2. Fit a resistor from this pin to ground to
set the peak current limit on the output inductor.
I
Soft-start pin for Buck2. Fit a small ceramic capacitor to this pin to set the
converter soft-start time.
O
Compensation pin for Buck2. Fit a series RC circuit to this pin to complete
the compensation circuit of this converter.
I
Feedback input for Buck2. Connect a divider set to 0.8 V from the output
of the converter to ground.
Forces PWM operation in all converters when set high. If low converters
will operate in automatic PFM/PWM mode.
Unused pin, connect to ground
Power good. Open drain output asserted low after all converters and
O
sequenced and within regulation. Polarity is factory selectable (active high
default).
O
Internal supply. Connect a 4.7-μF to 10-μF ceramic capacitor from this pin
to ground.
O
Internal supply. Connect a 3.3-μF to 10-μF ceramic capacitor from this pin
to ground.
Unused pin, connect to ground
