хочу взять выше 700 по GPU
Delta=0 и будет тебе счастье, на G71 дельта выше нуля.

OVERCURRENT PROTECTION
The individual channel currents, as sensed via the PHASE
pins and scaled via the ISEN resistor, are continuously
monitored and compared with an internal 95µA reference
current. If both channels’ currents exceed, at any time, the
reference current, the overcurrent comparator triggers an
overcurrent event. Similarly, an OC event is also triggered if
either channel’s current exceeds the 95µA reference for 7
consecutive switching cycles.
As a result of an OC event, output drives on both channels
turn off both upper and lower MOSFETs. The system then
waits in this state for a period of 4096 switching clock cycles.
The wait period is followed by a soft-start attempt. If the softstart attempt is successful, operation continues as normal.
Should the soft-start attempt fail, the ISL6563 repeats the
2048-cycle wait period and follows with another soft-start
attempt. This hiccup mode of operation continues indefinitely
(as depicted in Figure 4) for as long as the controller is
enabled or until the overcurrent condition is removed.
ищешь резистор идущий от 7-го вывода и если его сопротивление выше 1 кОм, закрашиваешь мягким карандашом и будет тебе счастье.
вроде так.
