POWER MANAGEMENT
The power consumption of UOC3 is ;
Only 3,3V_Stb is necessary for the start-up. IC internally produces 2,5V and 1,8V at the Standby
mode. After start-up necessary 1,8V are produced by external regulators. So, we have 3,3V_Stb, 5V,
5V_Stb and 1,8V. for UOC3. We don’t have 8V. even for audio outputs (1,2V RMS achieved with 5V).
All the voltages are produced by SMPS except 1,8V.
RESET :
1V8 digital and 1V8 analogue are produced by using 2V5 DECDIG-signal. DECDIG-signal is given
