2-11 Cigar Lighter Adaptor (CLA)
2-11-1 General Description
The CLA is a regulated switched-mode power supply designed for use with a portable HHP. The power supply is connected directly to the phone and provides a voltage path for charging a battery installed in the hand-held portable phone.

2-11-2 Circuit Description
The input voltage range of CLA is from 12 Vdc to 30 Vdc, and the nominal voltage is 13.7 Vdc. The output current is 600 mA. The ripple and noise amplitude is less than 50 mV at the input (12 V ~ 30 Vdc). And the limit settings are shown below; - Current limit : 600 mA ± 50 mA at nominal input 13.7 V - Output voltage : 9.0 V (+/- 0.8 V) Vdc at no load. In addition, the temperature limit is -20 upto +85 ¼C for storage, and 0 to +40 ¼C for operating. The CLA size of SGH-600 is 89.3 x 43 x 27 mm, and the weight is 110 g.

2-12 Travel Adaptor (TA)
2-12-1 General Description
