SNVSBB0A May 2019 – November 2019 ATL431LI-Q1 , ATL432LI-Q1
PRODUCTION DATA.
In the configuration shown, the ATL43xLI-Q1 acts as a control component within a feedback loop of the constant current sink. Working with an external passing component such as a BJT, the ATL43xLI-Q1 provides precision current sink with accuracy set by itself and the sense resistor RS. The LEDs are lit based on the desired current sink and regulated for accurate brightness and color.
