71 / 161 page  Analog Integrated Circuit Device Data Freescale Semiconductor 71 13892 FUNCTIONAL DEVICE OPERATION SUPPLIES SUPPLIES SUPPLY FLOW The switched mode power supplies and the linear regulators are dimensioned to support a supply flow based upon Figure 15. Figure 15. Supply Distribution While maintaining the performance as specified, the minimum operating voltage for the supply tree is 3.0 V. For lower voltages, the performance may be degraded. Table 43 summarizes the available power supplies. Table 43. Power Tree Summary Supply Purpose (Typical Application) Output Voltage (in V) Load Capability (in mA) SW1 Buck switcher for processor core(s) 0.600-1.375 1050 SW2 Buck switcher for processor SOG, etc. 0.600-1.375; 1.100-1.850 800 SW3 Buck switcher for internal processor memory and peripherals 0.600-1.375; 1.100-1.850 800 SW4 Buck switcher for external memory and peripherals 0.600-1.375; 1.100-1.850 800 SWBST Boost switcher for USB OTG, Tri-color LED drivers 5.0 300 VIOHI IO and Peripheral supply, eFuse support 2.775 100 VPLL Quiet Analog supply (PLL, GPS) 1.2/1.25/1.5/1.8 50 VDIG Low voltage digital (DPLL, GPS) 1.05/1.25/1.65/1.8 50 VSD SD Card, external PNP 1.8/2.0/2.6/2.7/2.8/2.9/3.0/3.15 250 VUSB2 External USB PHY supply 2.4/2.6/2.7/2.775 50 VVIDEO TV DAC supply, external PNP 2.5/2.6/2.7/2.775 350 VAUDIO Audio supply 2.3/2.5/2.775/3.0 150 Charger Protect and Detect SWBST 5.0V Coincell CC Charge RTC, MEMA/B SW1 GP Core DVS Domain External Memory Viohi Vcore Vcam Core SD, Tflash Camera IO and Digital Peripherals IO, EFUSE GPOs 0.6 to 1.15V VGEN3 Peripherals Vsd Vpll Core PLLs (Analog) Battery Voltage & Current Control BP Power Audio Coin Cell Peripherals SW4 1.8V SW2 0.6 to 1.25V PGATE Vdig GPS Core VGEN1 WLAN, BT VGEN2 MLC NAND Alternate hardwired bias option from external 2.2V switcher Vcoredig Processor Interfaces PNP PNP PNP PNP Serial Backlight Drivers System Supplies External Loads Internal Loads Energy Source Legend SOG Core DVS Domain SW3 1.25V Internal Processor Memory PNP PNP Accessory USB Cable Interface UVBUS VVIDEO PNP VAUDIO Audio TV-DAC PNP VUSB USB PHY PGATE Peripherals VUSB2 Alternate hardwired bias option from SW4 |
