Hello,
The ZXLD1370 buckboost led driver offers very accurate led current regulation even though it puts the sense resistor in series with the inductor and not the LEDs.
Do you believe that the graph of figure 18 on page 13 of the datasheet would show the led current not varying much with input voltages extending up to 30V?
Achieving the current accuracy claimed in the datasheet (in spite of line and load voltage changes) in buckboost mode when the led current is not being directly sensed, is, I think you will agree, pretty fantastic. Can it really be this good? No other IC datasheet makes these claims.

Also, why in the zxld1370 datasheet, on pages 2, 15 and 36, does it show the output capacitor going to ground, instead of being across the leds, when in buckboost mode?
