说明
- Evaluation Board for This wide input voltage range boost operates from an input of 9V - 32V and regulates current in two strings of 13 LEDs. A second control loop monitors and regulates the input current during drop outs or faults. Discrete linear regulators at the bottom of each string control the individual string current while feedback minimizes the output voltage based on the LED voltage mismatch or shorts. This low cost design operates at near 94% efficiency
