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
Channel 1 current sense negative input.
Connect through a Rg resistor to the output-side of the channel 1 inductor.
See “Layout guidelines” Section
Soft-start oscillator, LTB gain and AMD selection pin.
It allows selecting between INTEL DACs and AMD DAC.
Short to SGND to select AMD DAC otherwise INTEL mode is selected.
When INTEL mode is selected trough this pin it is possible to select the soft-
start time and also the gain of LTB Technology™.

Oscillator pin.
It allows programming the switching frequency F
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 8 kHz/µA (see relevant section for details).
Leaving the pin floating programs a switching frequency of 200kHz per phase.
The pin is forced high (5 V) to signal an OVP FAULT: to recover from this
condition, cycle VCC or the OUTEN pin.

DVID - AMD mode. DVID output.
CMOS output pulled high when the controller is performing a D-VID transition
(with 32 clock cycle delay after the transition has finished).
