20.2. Power Supply Circuit
The power is supplied to the DECT BBIC, RF Module, EEPROM, SP AMP, LED from AC Adaptor (+6V) as shown in Fig.101.
The power supply is as follows;
• • • • DECT BBIC (IC2): CN2(+6V) → L8 → D1 → IC1 → Q2 → IC2
• • • • RF Module (RFM1): CN2(+6V) → L8 → D1 → IC1 → RF Module
• • • • EEPROM (IC3): CN2(+6V) → L8 → D1 → IC1 → Q2 → IC3
• • • • Flash Memory (IC7): CN2(+6V) → L8 → D1 → IC1 → Q2 → IC7
• • • • SP AMP (IC10): CN2(+6V) → L8 → D1→ IC14 → IC10
• • • • Logic IC (IC12, IC13): CN2(+6V) → L8 → D1 → IC1 → Q2 → IC12, IC13
• • • • LCD (CN502): CN2(+6V) → L8 → D1 → IC1 → Q2 → CN9 → CN501 → CN502(LCD)
• • • • LED (LED501, LED502, LED503, LED504): CN2(+6V) → L8 → D1 → IC14 → CN9 → CN501 → LED
• • • • OP AMP (IC15): CN2(+6V) → L8 → D1→ IC14 → IC15
