3.3. Power management IC
KS660 is composed of dual Power Management Part. (S-Gold3 & S-Gold Radio)
3.3.1. S-Gold3 Part
3.3.1.1. General Description
SM-POWER is a highly integrated Power and Battery Management IC for mobile handsets. It has been
specially designed for usage with S-Gold3. Although optimized for usage with the Infineon S-GOLD
baseband device it is suitable for the S-GOLDlite and the E-GOLD+ baseband devices as well. It also
supports the cellular RF devices like SMARTi-DC, SMARTi-DC+, SMARTi-SD and the Bluemoon Single,
Infineon’s single chip solution for Bluetooth. If used with S-GOLD3 it provides all power supply functions
(except for the RF PA) for a complete advanced GSM Edge smart phone minimizing external device
count.
