Pin description and connection diagram

8LTB
Load transient boost pin.
Internally fixed at 2 V, 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.
9IMON
Current monitor output pin.
A current proportional to the load current is sourced from this pin. Connect through a resistor
RMON to FBG to implement a load indicator. Connect the load indicator directly to VR11.1
CPUs.The pin voltage is clamped to 1.1 V max to preserve the CPU from excessive voltages.
10
LTBGAIN
Load transient boost technology gain pin.
Internally fixed at 1.24 V, connecting a RLTBGAIN resistor vs SGND allows setting the gain of
11
OFFSET
Offset programming pin.
Internally fixed at 1.240 V, connecting a ROFFSET resistor vs. SGND allows setting a current
that is mirrored into FB pin in order to program a positive offset according to the selected RFB.
Short to SGND to disable the function.
12
OVPSEL
Overvoltage programming pin. Internally pulled up by 20 A (typ) to 3.3 V.
Leave floating to use built-in protection thresholds (OVPTH = VID + 175 mV typ).
Connect to SGND through a ROVP resistor and filter with 100 pF (max) to set the OVP
threshold to a fixed voltage according to the ROVP resistor.
Connect to SGND to select VR10/VR11 table. In this case the OVP threshold becomes
1.800 V (typ).
13
OCSET/
PSI_A
Overcurrent setting, PSI action pin.
Connect to SGND through a ROCSET resistor to set the OCP threshold for each phase.
It also allows to select the number of phase when PSI mode is selected.
14
OSC/
FAULT
Oscillator, FAULT pin.
It allows programming the switching frequency FSW of each channel: the equivalent switching
frequency at the load side results in being multiplied by the phase number N.
Frequency is programmed according to the resistor connected from the pin vs. SGND or VCC
with a gain of 9.1 kHz/A (see relevant section for details).
Leaving the pin floating programs a switching frequency of 200 kHz per phase.
The pin is forced high (3.3 V typ) to signal an OVP/UVP fault: to recover from this condition,
cycle VCC or the OUTEN pin. See “Oscillator” Section for details.
15
SSOSC
Soft-start oscillator pin.
By connecting a resistor RSS to GND, it allows programming the soft-start time.
Soft-Start time TSS will proportionally change with a gain of 25 [s / kΩ]. The same slope
implemented to reach VBOOT has to be considered also when the reference moves from
VBOOT to the programmed VID code. The pin is kept to a fixed 1.240 V.
