LM36010EVM User Guide

LED Current Measurements, D1F, D1S, GNDS (Jumper J14) –

The LM36010EVM provides a way to

accurately measure the LED current through the LED on board. Resistor R4 (0.1

Ω

) is placed between the

cathode of LED (D1F) and ground. The user can first measure the resistor value accurately by first
applying a known current through force pin (D1F) and ground and measuring the voltage between sense
pin (D1S) and GNDS. Then, during normal flash or torch operation, the voltage measured across the
resistor divided by the resistor value will equal the current through the resistor (or the LED).
