Explanation of Chapter "Electricity"
1. Outline of power supply system and control system
①
Periphery of power supply
①
-1: Main power supply: DC - IN (9V), or rechargeable EN-EL3 lithium ion battery (7.4V)
When the external pack is used (lithium ion: 2 pcs., or AA dry battery: 6 pcs.)
Built-in clock: Secondary battery 3V 65mAH
①
-2: DC/DC converter
By this DC/DC converter, DC voltage of 3.5V~10.8V is inputted and nine kinds of voltage for
the following eight systems are outputted.
• +1.1V (VCC1.1)
• +1.8V (VCC1.8)
• +3.3V (VCC3)
• +4.0V (VCC4)
• +7.0V (VCC7)
• +5.125V (VCC5B)
• +18.0V (VCC18A, VCC18B)
• -8.0V (VCC-8)
Output is controlled by the control terminals of two systems.
The control terminal CTL1 controls VCC4, VCC7, VCC18A and VCC-8.
The control terminal CTL2 controls VCC1.1, VCC1.8, VCC3, VCC5B and VCC18B.
