TC1765
Preliminary
Power Supply
Figure 18 shows the TC1765âs power supply concept, where certain logic modules are
individually supplied with power. This concept improves the EMI behavior by reduction
of the noise cross coupling. Also the operation margin is improved in sensitive modules
like the A/D converter by noise reduction.
