Simple open-circuit protection for boost converters in LED driver
... the deviation from the expected load current was calculated (see Equation 10 below). The datasheet value of 200 nA was used for the feedback bias current (IFB), and a value of 1 µA was used for the expected leakage current through the Zener diode, with a VOUT of approximately 10 V. Recall that the i ...
