Pin settings
L6714
8/70
15
VCC
Device supply voltage. The operative voltage is 12V ±15%. Filter with 1F (typ)
MLCC vs. SGND.
16
DAC/
CS_SEL
DAC and Current Sense SELection Pin.
This pin sources a constant 12.5A current. By connecting a resistor vs. SGND
it is possible to select between Intel and AMD integrated DACs and Current
Sense methods.
Filter with 100pF(max) vs. SGND.
DACs and Current Sense methods cannot be changed dynamically.
See “DAC selection” Section and See Table 10 for details.
17
OUTEN
OUTput ENable Pin.
Forced low, the device stops operations with all MOSFET OFF: all the
protections are disabled except for Section 16.2: Preliminary over voltage on
Set free, the device starts-up implementing soft-start up to the selected VID
code.
Cycle this pin to recover latch from protections; filter with 1nF (typ) vs. SGND.
18
SSOSC/
REF
Intel Mode. Soft Start OSCillator Pin.
By connecting a resistor RSSOSC vs. SGND, it allows programming the frequency
FSS of an internal additional oscillator that drives the reference during Soft-Start.
Setting this frequency allows programming the Soft-Start time TSS proportionally
to the RSSOSC connected with a gain of 20.1612 [s / k]. The same slope
implemented to reach VBOOT has to be considered also when the reference
details.
AMD Mode. REFerence Output. Filter with 47
- 4.7nF vs. SGND.
19
SGND
All the internal references are referred to this pin. Connect to the PCB Signal
Ground.
20
VSEN
Remote Buffer Output, it manages OVP and UVP protections and PGOOD
(when applicable). See “Output voltage monitor and protections” Section and
See Table 10 for details.
21
DROOP
A current proportional to the total current read is sourced from this pin according
to the Current Reading Gain.
Short to FB to implement Droop Function or Short to SGND to disable the
function.Connecting to SGND through a resistor and filtering with a capacitor,
the current info can be used for other purposes.
22
FB
Error Amplifier Inverting Input. Connect with a resistor RFB vs. VSEN and with an
RF - CF vs. COMP.
23
COMP
Error Amplifier Output. Connect with an RF - CF vs. FB.
The device cannot be disabled by pulling down this pin.
24
CS4+
Channel 4 Current Sense Positive Input.
LS Mosfet Sense: connect through a resistor Rg to the LS mosfet Source.
Inductor DCR Sense: connect through an R-C filter to the phase-side of the
channel 4 inductor.
See “Layout guidelines” Section for proper layout of this connection.
