CURRENT CONTROL

The voltage at pins CI1/2/B sets the current in pins

LDK1/2/B. Figures 2 and 3 show the temperature de-

pendency of the current in a single LDKx output versus

the voltage at CIx for a typical device. Figures 4 and

5 show the min., typ. and max. variations between de-

vices at 27 °C temperature.

Figure 2: I(LDK1/2) vs. V(CI1/2) at VDD = 5 V

Figure 3: I(LDK1/2) vs. V(CI1/2) at VDD = 3.3 V

Figure 4: I(LDKx) vs. V(CIx) at VDD = 5 V

Figure 5: I(LDKx) vs. V(CIx) at VDD = 3.3 V

DEMO BOARD

iC-HB comes with a demo board for test purpose. Figures 6 and 7 show both the schematic and the component

side of the demo board.
