TPS61220

I want to set output to 6.0V, what resistor values are the best R1 and R2 ?

Does TPS61220 output 6.0V?

TPS61070

I want to set output to 5.5V, what resistor values are the best R1 and R2 ?

Does TPS61070 output 5.5V?

Hi Umino,

TPS61220 can't output 6V, the max is 5.5V. And TPS61070 can output 5.5V.

I have 3 questions.

1.TPS61220

The following description is on the data sheet of TPS61220.

Adjustable Output Voltage from 1.8 V to 6 V.

Why TPS61220 can't output 6V, refer the datasheet of TPS61220.

2. What are the resistance values of R1 and R2 for 6V output ?

3. What are the resistance values of R1 and R2 for 5.5V output at TPS61070 ?

Hi Umino,

Sorry about the mistake. The output of TPS61220 can be as high as 6V . You can set R1=100koms, R2=1100kohms.

For TPS61070. The 5.5V output, R1=100koms, R2=1000kohms.

Refer to the equation in Datasheet : Programming the output voltage to set different output .
