I have a LED driver operating on Vin 48 V, Vout 32 V, and Iout = 4Amp. Twelve LEDs in series and in parallel with four sets. So, an amp through each leg. The current is not regulated to 4 amps, less than an amp measured with a Fluke RMS meter. Measured all the feedback controls, reference voltages, etc. and they all look in the proper order. Voltage at CTRL1 is 2V, CNTL2 is 1.88V.
SW signal shows a 2MHz ring.
Do you have an idea what is preventing the proper current output? What else can I measure and post?
