Pin settings
L6713A
8/64
18
LTB
Load Transient Boost Pin.
Internally fixed at 1V, connecting a RLTB - CLTB vs. VOUT allows to enable the
Load Transient Boost Technology: as soon as the device detects a transient
load it turns on all the PHASEs at the same time. Short to SGND to disable the
function.
19
SGND
All the internal references are referred to this pin. Connect to the PCB Signal
Ground.
20
VSEN
It manages OVP and UVP protections and PGOOD (when applicable).
See “Output voltage monitor and protections” Section.
100A constant current (IOFFSET, See Table 4) is sunk by VSEN pin in order to
generate a positive offset in according to the ROFFSET resistor between VSEN
pin and VOUT. See “Offset (Optional)” Section 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
N.C.
Not internally connected.
25
N.C.
Not internally connected.
26
CS2+
Channel 2 Current Sense Positive Input.
Connect through an R-C filter to the phase-side of the channel 2 inductor.
Short to SGND or to VOUT when using 2 Phase operation.
See “Layout guidelines” Section for proper layout of this connection.
27
CS2-
Channel 2 Current Sense Negative Input.
Connect through a Rg resistor to the output-side of the channel 2 inductor.
Leave floating when using 2 Phase operation.
See “Layout guidelines” Section for proper layout of this connection.
28
CS3+
Channel 3 Current Sense Positive Input.
Connect through an R-C filter to the phase-side of the channel 3 inductor.
See “Layout guidelines” Section for proper layout of this connection.
29
CS3-
Channel 3 Current Sense Negative Input.
Connect through a Rg resistor to the output-side of the channel 3 inductor.
See “Layout guidelines” Section for proper layout of this connection.
30
CS1+
Channel 1 Current Sense Positive Input.
Connect through an R-C filter to the phase-side of the channel 1 inductor.
See “Layout guidelines” Section for proper layout of this connection.
31
CS1-
Channel 1 Current Sense Negative Input.
Connect through a Rg resistor to the output-side of the channel 1 inductor.
See “Layout guidelines” Section for proper layout of this connection.
