ISL9444EVAL1Z: 1.05V, 1.8V, 3.3V @ 6A, 6 ~ 20V in

Summary

The ISL9444EVAL1Z evaluation board (shown in Figure 1) features the ISL9444. The ISL9444 is a triple-output synchronous buck controller that integrates three PWM controllers. The ISL9444 offers external soft-start, independent enable functions and integrates UV/OV/OC/OT protection. Its current mode control architecture and internal compensation network keep peripheral component count minimal.

Programmable switching frequency ranging from 200kHz to 1200kHz helps to optimize inductor size while the strong gate drivers deliver up to 25A for each PWM channel.
