TPS61161-Q1: Max output current for LED

Roy Chou1

Part Number: TPS61161-Q1

Team,

What is the max value of LED output current? I see the 20mA spec in ti.com. but i seems like we could support up to 80mA in datasheet.

Team,

If our use case is showing as below. 3.1V/20mA/LED, 4 LED need 80mA. Our Vin is stable 3.0V. Could TPS61161-Q1 support?

Team,

Could anyone confirm my question?

Hi Roy,

I suggest to series the 4LED since you can't control the brightness of each LED when parallel, either.
