I'm testing boost convertor with LT3517 and I have lower output current than expected. Input voltage is 12V or higher, output voltage depend on condition, but max 37V and out current should be 200mA. I have 0R47 resistor between pin ISP and ISN…
Per data sheet (p.9) of the LT3517, when the CTRL pin voltage is less than 1V, the LED current is: ILED =VCTRL/(10*RSENSE).
Question: What precision of this equation in temperature range of +10 to +50 Celsius degrees?
Please check these: the analog dimming is not as fine though.
