Hi Robin,
Good day !
I finally managed to get the display backlight circuitry working with TPS 61500. Below are waveform captured at the Vout , inductor and Iled current ( 360mA ) .
Appreciate your guidance whether is there abnormality with respect to the these capturing.
With the bandwidth of the voltage probe adjusted from 20Mhz to 250Mhz , there is more switching surges observed is this normal ?
Thks & Rdgs
