This document introduces the LED driver evaluation board based on L6902D, including input voltage, dimming interface, analog current control and average current control by PWM.
The STEVAL-ILLO10V1 is an evaluation board designed for high intensity LED dimming applications. It is built around the L6902 DC-DC converter and implements two dimming methods: analog current control and average current control via PWM. The board allows users to test these dimming techniques using a single input connector.
| Input voltage | 8 V to 30 V |
|---|---|
| Maximum output current | 350 mA |
| Analog dimming voltage range | 0 to 3.3 V |
| PWM dimming voltage | 3.3 V or 5 V |
| Base IC | L6902 |
The board implements both analog current control and average current control by PWM.
The input voltage range is 8 V to 30 V.
A signal between 0 and 3.3 V should be used for analog current control.
