Additionally, the ADP1032 contains four high speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where low power dissipation and small solution size is required. Operating over an input voltage range of 4.5 V to 60 V, the ADP1032 generates isolated output voltages of 6 V to 28 V (adjustable version) or 24 V (fixed version) for VOUT1, and factory programmable voltages of 5.15 V, 5.0 V, or 3.3 V for VOUT2. By default, the ADP1032 flyback regulator operates at a 250 k Hz switching frequency, and the buck regulator operates at...
