The ISL68137 is a digital +output 7-phase configurable PWM controller with an AVSBus interface. 2nd +generation devices are grouped into 4 distinct configurations: '1rail' for +single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices, +and 'hv' for high voltage single-rail devices.
