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 the PHASE. Short to SGND to disable the function.See “Load
transient boost technology” Section for details.
9IMON
Current monitor output pin.
A current proportional to the load current is sourced from this pin. Connect
through a resistor RMON to SGND (or FBG) to implement a load indicator. The
pin voltage is clamped to 1.1 V max.
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 the LTB action. See See “Load transient boost technology”
Section for details.
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.
See “Offset (optional)” Section for details.
12
OVPSEL
Over voltage programming pin.
Internally pulled up by 20 A (min) 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
OVP” Section for details.
13
OCSET
Over current setting, psi action pin.
“Overcurrent protection” Section for details.
14
OSC/
FAULT
Oscillator, fault pin.
It allows programming the switching frequency FSW. 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. 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/
FLIMIT
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. See “Soft-start” Section for details. It also allows to select
maximum LTB frequency. See “Load transient boost technology” Sectionfor
details.
