There are several chip board, only use a 3.3 V voltage regulator chip driver can

CodePudding user response:

Or a chip need a separate power supply voltage chip?

CodePudding user response:

Depending on the current, just 3.3 V power is large enough,

CodePudding user response:

You are micro power consumption system, must be, otherwise the overall design has a problem!

CodePudding user response:

Complete enough, unless there is a high power output

CodePudding user response:

Enough to use depends on whether the output power of 3.3 V power supply chip chip using enough,

CodePudding user response:

Current enough, not to see how much, to be calculated

CodePudding user response:

Calculate the power consumption of each chip and power supply voltage is the same, the same even if the total power consumption can leave 20% allowance

CodePudding user response:

If the voltage is 3.3 V are the same, whether power is enough, is regulated power supply continuous power supply ability whether meet the needs of all electricity chip; In addition, if there are some large current or power chip high frequency signal, and other best chip separate power supply, electricity is to use different voltage chip, power supply, at the very least to shunt power supply, intermediate can be separated with 0 ohm resistor or magnetic beads,
