Fig 6 1 for basic operation V1 supplies the DSC bus drivers negative voltage regulators and MAGIC V1 is created from GCAP II Pin A6 and can be measured on C906 B FREAK LX J Fig 6 1 Output The basic circuit operation for the Boost circuit is as follows the LX signal GCAP II Pin B10 allows a path for B to charge the capacitor when the switch is on the capacitor then discharges through the inductor switch off setting up an electric field The field then collapses setting up a back EMF to charge the capacitor and so on and so on The back EMF created by the inductor is greater than B with the ve half of the cycle passing through the diode to charge a capacitor from where the V_BOOST voltage is taken The frequency of the switching signal LX decides the duty cycle of the output wave and therefore the resultant voltage V_BOOST is fed back into the GCAP V2 Programmed to 2 775V available whenever the radio is on and supplies most of the logic side of the board V2 is supplied out of GCAP II Pin J2 and can be measured on either C939 or C941 V3 Programmed to 2 003V to support the Whitecap but does support the normal 2 75V logic output from the Whitecap it originates from GCAP II Pin B5 and can be measured on C909 or C910 VSIMI Used to support either or SV SIM cards Will dynamically be set to upon power up but if the card cannot be read then the SIM card is powered down and an attempt to read the card at 5V
