33 / 118 page  Analog Integrated Circuit Device Data Freescale Semiconductor 33 PF0200Z Functional Block Requirements and Behaviors Power Generation Figure 9 shows a simplified power map with various recommended options to supply the different block within the PF0200Z, as well as the typical application voltage domain on the i.MX 6 application processors. Note that each application power tree is dependent upon the system’s voltage and current requirements, therefore a proper input voltage should be selected for the regulators. The minimum operating voltage for the main VIN supply is 2.8 V, for lower voltages proper operation is not guaranteed. However at initial power up, the input voltage must surpass the rising UVDET threshold before proper operation is guaranteed. Refer to the tables and text specifying each supply for information on performance metrics and operating ranges. Table 27 summarizes the UVDET thresholds. Table 26. Power Tree Summary Supply Output Voltage (V) Step Size (mV) Maximum Load Current (mA) SW1A/B 0.3 - 1.875 25 2500 SW2 0.4 - 3.3 25/50 1500 SW3A/B 0.4 - 3.3 25/50 1250(36) SWBST 5.00/5.05/5.10/5.15 50 600 VGEN1 0.80 – 1.55 50 100 VGEN2 0.80 – 1.55 50 250 VGEN3 1.8 – 3.3 100 100 VGEN4 1.8 – 3.3 100 350 VGEN5 1.8 – 3.3 100 100 VGEN6 1.8 – 3.3 100 200 VSNVS 1.0 - 3.0 NA 0.4 VREFDDR 0.5*SW3A_OUT NA 10 Notes 36. Current rating per independent phase, when SW3A/B is set in single phase, current capability is up to 2500 mA. Table 27. UVDET Threshold UVDET Threshold VIN Rising 3.1 V Falling 2.65 V |
