TPS61222: How can i configure Vout=5V and Iout=150mA max

Jun Xian Low

Part Number: TPS61222

I am going to have an input of 2.7v to 4.2v, I need Vout=5V and Iout=120mA for my system load.

This TPS61222 is able to give Vout= 5V max and Iout=200mA maximum right?

How can i configure it to be Vout=5V and Iout=150mA maximum for my system load? I need some help on this based on the datasheet. Thanks.

Hi Jun:
The maximum output current related with Vin and Vout. And I'm sorry to tell you it will have risk when Vin=2.7V, Vout=5V Iout=150mA. You could see the Figure 1. "Maximum Output Current versus Input Voltage" in datasheet. But the bias is not large.
So could you confirm the load is 150mA for whole input Vin range?
