BOOST structure carries out pressure stabilizing, could export answering machine 200 and work required steady state voltage (representative value 3.3V).Pressure stabilizing list
Member 322 the course of work are as follows: when 321 unit output voltages be greater than V value, automatically enable BUCK (decompression) function, when Unit 321 are defeated
Voltage is less than V value out, enables BOOST (boosting pressure) function, transfer efficiency 95%, maximum output current 1A automatically.
The above are the discrete power supply models in mixed signal to pass through 320 and 330 modules, and it is defeated to form linear stable state power supply signal
