FB1 The feedback network of the Channel 1 regulator.

FB1 is the negative input to the transconductance error amplifier.

voltage is set by an external resistor divider connected to FB1.

include internal digital soft-start, enable for power sequence, overcurrent protection, and thermal shutdown. The ISL78228 is offered in a 3mmx3mm 10 Ld DFN package with 1mm maximum height. The complete converter occupies less than 1.8cm2 area. The ISL78228 is AEC-Q100 qualified and is rated for the automotive temperature range (-40°C to +105°C). Features.
Internal current mode compensation.
100% maximum duty cycle for lowest dropout.
Selectable forced PWM mode and PF.
