19. SECTION 4 THEORY OF OPERATION 4 22 3 SYSTEM POWER Along with the unregulated VMOT supply a secondary switching regulator provides system power The secondary switching regulator includes IC U4 transformer Tl and transistors Q4 and Q5 The regulator is a triple output wide supply range fly back converter that provides regulated 3 3 Vpc 5 Vpc and 12 Vpc outputs from the five winding transformer T1 The regulator operates over an input range of 4 to 10 Vpc and provides output current limit as well as voltage overshoot limit Primary feedback is metered through a bias arrangement on transistor Q3 A Schottky rectifier diode CR4 provides feedback in the event of V3 3 or V12 O0 failure and transistor Q10 provides feedback in the event of V5 O0 failure The positive terminal of the battery provides the raw DC voltage VMOT for the motors and backlight of the display 4 224 AUXILIARY SUPPLIES The power supply subsystem provides full time 5 Vpc and 2 7 Vpc supplies that are active when battery or AC voltage is present The full time 5 Vpc supply VSC uses a linear low dropout voltage regulator U6 whose power source is directly from the battery and is backed up by a 0 1 F capacitor VSC is used for the ON OFF switch and a power failure alarm latch The full time 2 7 Vpc supply V2 7 is derived from VSC and is used to supply the ultra low current needed to power the real time clock and non volatile SRAM during shutdown 4 22 5 POWER CONTRO
