The ISL9440EVAL2Z evaluation board features the ISL9440 triple, 180° out-of-phase, step-down PWM and single linear controller. The ISL9440 is a quad-output controller that integrates three PWM synchronous buck controllers and one low-dropout linear regulator controller. The ISL9440 offers internal soft-start, independent enable functions and integrates UV/OV/OC/OT protections. Its current mode control architecture and internal compensation network keep peripheral component count minimal. A switching frequency of 300kHz minimizes losses while the strong gate drivers deliver up to 12A to each PWM channel.
