TLV61046A: Is it possible to do current controlled output with this chip

Connor Redding

Part Number: TLV61046A

I'm trying to power 8 LEDs off of a LiPo battery. The forward voltage per LED ranges from 2.7 to 3.1, but want 5 mA. Is it possible to do current controlled output with this chip, a boost converter in general, or should I look to use a current limiting diode.

Hi Cornnor,

please refer to this application note, using a resistor to limit the LED current. (need to change the device and the numbers of the LED according your application)
