2. Functional Description Functional Description The ISL81601VAL2Z is the same test board used by Renesas application engineers and IC designers to evaluate the performance of the ISL81601 HTSSOP IC. The board provides an easy and complete evaluation of all the IC and board functions. - Page 5 ISL81601EVAL2Z 2. Functional Description Quick Test Guide (1) Jumper J8 provides the option to select PWM or DEM. Jumper J9 provides the option to select Constant current limit or HICCUP. Refer to Table 2 for the operating options. Ensure that the circuit is correctly connected to the supply and electronic loads prior to applying any power.

Page 7: Pcb Layout Guidelines
ISL81601EVAL2Z 3. PCB Layout Guidelines PCB Layout Guidelines Careful attention to layout requirements is necessary for successful implementation of an ISL81601 based DC/DC converter. The ISL81601 switches at a very high frequency; therefore the switching times are very short. At these switching frequencies, even the shortest trace has significant impedance. - Page 8 ISL81601EVAL2Z 3. PCB Layout Guidelines ISL81601VAL2Z Evaluation Board Figure 5.
