SBAS562B April 2012 – December 2019 AMC1100
PRODUCTION DATA.
The high-side supply for the AMC1100 can be derived from the phase voltage using a capacitive-drop power supply (cap-drop), as shown in Figure 39 and described in the application report SLAA552, AMC1100: Replacement of Input Main Sensing Transformer in Inverters with Isolate Amplifier.
Alternatively, the high-side power supply for each AMC1100 can also be derived from the low-side supply using the SN6501 to drive a transformer, as proven by the TI reference design TIPD121, Isolated Current Sensing Reference Design Solution, 5A, 2kV.
