SAMPLE POWER SUPPLY USING CHANNEL 8 AS SELF-POWER SUPPLY
Using channel 8 as the self-power supply, the MB3881 can support a wide range of supply voltages and operate
at low input voltage (Vin
≥
1.8 V).
The following example shows sample power supply using a transformer.
The following settings are used in “APPLICATION EXAMPLE”.
VSS(O) is set to the number of turnings that produces Vin - 1.8 V.
VCC and VCC(O) are set to the number of turnings that produces Vin + 2.2 V.
Note that, because channels 1 to 4 operate at VCC
≥
4 V, they must be set to the number of turnings that
produces Vin + 2.2 V or more so that they operate at Vin
≥
1.8 V.
