4-3 Special Circuit Descriptions

4-3-1 Power Circuit

This system is operated under 100Vac or 240Vac. The power circuit supplies the three differential DC voltage sources.

[Figure 4-3 Power Block Diagram]

1)Drawer Driving and Feed, Auto Cutter Motor Voltage and TPH Driving Voltage: +24VDC +24VDC is supplied from SMPS. This Voltage is smoothed by capacitors (CE1).

This voltage is used as a Cash Drawer Solenoid Driving voltage, Step motor driving voltage and a source voltage of the other voltage sources and TPH Driving Voltage.

2)IEEE1284 Logic IC Driving Voltage: +5VDC

Step down voltage the input +24VDC to +5VDC by a switching regulation U13(A4490SES-T)

3) CPU I/O, FPGA I/O, NAND Flash and etc. LOGIC Voltage: +3.3VDC

Step down voltage the input +5VDC to +3.3VDC by a regulation.U15(SI-3006KWM)

4) CPU A/D, USB core and OSC Voltage: +2.5VDC

Step down voltage the input +24VDC to +2.5VDC by a switching regulation.U13(A4490SES-T)

5) DDR2 Voltage: +1.8VDC

Step down voltage the input +5VDC to +1.8VDC by a regulation.U15(SI-3006KWM)
