PIN FUNCTION
N. (*)
Name
Description
SO
VFQFPN
1
33
LGATE1
Channel 1 LS driver output.
A little series resistor helps in reducing device-dissipated power.
2
34
VCCDR
LS drivers supply: it can be varied from 5V to 12V buses.
Filter locally with at least 1
µF ceramic cap vs. PGND.
3
35
PHASE1
Channel 1 HS driver return path. It must be connected to the HS1 mosfet source
and provides the return path for the HS driver of channel 1.
4
36
UGATE1
Channel 1 HS driver output.
A little series resistor helps in reducing device-dissipated power.
5
2
BOOT1
Channel 1 HS driver supply. This pin supplies the relative high side driver.
Connect through a capacitor (100nF typ.) to the PHASE1 pin and through a diode
to VCC (cathode vs. boot).
6
4
VCC
Device supply voltage. The operative supply voltage is 12V ±10%.
Filter with 1
µF (Typ.) capacitor vs. GND.
7
5,6
SGND
All the internal references are referred to this pin. Connect it to the PCB signal
ground.
8
7
COMP
This pin is connected to the error amplifier output and is used to compensate the
control feedback loop.
9
8
FB
This pin is connected to the error amplifier inverting input and is used to
compensate the control feedback loop.
10
9
DROOP
A current proportional to the sum of the current sensed in both channel is
sourced from this pin (50
µA at full load, 70µA at the Constant Current threshold).
Short to FB to implement the Droop effect: the resistor connected between FB
and VSEN (or the regulated output) allows programming the droop effect.
Otherwise, connect to GND directly or through a resistor (43k
Ω max) and filter
with 1nF capacitor. In this last case, current information can be used for other
purposes.
11
11
REF_IN /
OUT
Reference input/output. Filter vs. GND with 1nF ceramic capacitor (a total of
100nF capacitor is allowed).
It reproduces the reference used for the regulation following VID code: when
VID=111, the reference for the regulation must be connected on this pin.
References ranging from 0.800V up to 3.300V can be accepted.
12
12
VSEN
Connected to the output voltage it is able to manage Over & Under-voltage
conditions and the PGOOD signal. It is internally connected with the output of the
Remote Sense Amplifier for Remote Sense of the regulated voltage.
Connecting 1nF capacitor max vs. GND can help in reducing noise injection at
this pin.
If no Remote Sense is implemented, connect it directly to the regulated voltage in
order to manage OVP, UVP and PGOOD.
13
13
ISEN1
Channel 1 current sense pin. The output current may be sensed across a sense
resistor or across the low-side mosfet RdsON. This pin has to be connected to the
low-side mosfet drain or to the sense resistor through a resistor Rg.
The net connecting the pin to the sense point must be routed as close as
possible to the PGNDS net in order to couple in common mode any picked-up
noise.
14
14
PGNDS1
Channel 1 Power Ground sense pin. The net connecting the pin to the sense
point must be routed as close as possible to the ISEN1 net in order to couple in
common mode any picked-up noise.
15
15
PGNDS2
Channel 2 Power Ground sense pin. The net connecting the pin to the sense
point must be routed as close as possible to the ISEN2 net in order to couple in
common mode any picked-up noise.
