9 Power Supply Recommendations
In a typical frequency-inverter application, the high-side power supply (AVDD) for the AMC1336-Q1 is generated from the controller-side supply (DVDD) of the device by an isolated dc/dc converter circuit. Figure 54 shows a low-cost solution based on the push-pull driver SN6501 and a transformer that supports the desired isolation voltage ratings. TI recommends using a low-ESR decoupling capacitor of 0.1 µF and an additional capacitor of minimum 1 µF for both supplies of the AMC1336-Q1. Place these decoupling capacitors as close as possible to the device power-supply pins to minimize supply current loops and electromagnetic emissions.
The AMC1336-Q1 does not require any specific power up sequencing. Consider the analog settling time tASTART as specified in the Table 10 table after ramp up of the AVDD high-side supply.
Connect the high-side ground pin AGND of the AMC1336-Q1 to one of the analog inputs AINx to avoid common-mode input voltage range violations.
