... The ISL6217 PGOOD pin is both an input and an output. The system signal, IMVP4_PWRGD, is connected to power good signals from the Vccp and Vcc_mch supplies. The Intersil ISL6227, Dual Voltage Regulator is an ideal choice for the Vccp and Vcc_mch supplies. Once the output voltage is within the “Boot” level regulation ...
