PIN FUNCTIONS
N
Name
Description
1,2,3,
23,24
VID4-0
Voltage Identification inputs. VID0 is the LSB and VID4 is the MSB for the DAC (see VID table)
4
CS-
This pin is used for both current sensing and to detect overvoltage and undervoltage
conditions.
5
CS+
Current sense pin. Overcurrent condition is detected by sensing CS+ to CS- voltage.
6
VCC
Supply voltage for analogy blocks. Connect it to 5V bus.
7
GND
Signal ground
8
VPROG
DAC output voltage. This pin provides the voltage programmed by the DAC. Connect a 10nF
capacitor between this pin and GND.
9
VFB+
PWM comparator reference input. Connect this pin to VPROG.
An additional external voltage divider between output and VPROG may be used to realize the
active droop function.
10
VFB-
PWM comparator feedback input, to be connected to the regulated output.
By inserting a resistor between this pin and the regulated output, a positive offset can be
added to the output voltage.
11
OSC
Connect this pin to the battery through a voltage divider in order to provide the voltage
feedforward feature.
12
SS
Soft start pin. 5
A constant current charges an external capacitor whose value sets the soft-
start time.
13
ILIM
An external resistor connected between this pin and GND sets the current limit threshold.
14
SHDN
ShutDown input. When connected to GND the device stops working. When high, it enables
the IC operation.
15
OVP
Open drain output. The pull-down transistor is off either in OV condition or during a VID
transition.
16
PGOOD
Open drain output. The pull-down transistor is on during soft-start, dynamic transitions and
when an output voltage fault occurs.
17
PGND
Power Ground. This pin has to be connected close to the low side MOSFET source in order to
minimize switching noise.
18
LGATE
Lower MOSFET gate driver output.
19
VDR
Voltage supply for the low side internal driver.
20
PHASE
This pin provides the return path of the high side driver.
21
HGATE
High side MOSFET driver output.
22
BOOT
Bootstrap capacitor pin. The high side driver is supplied through this pin.
