NOTICE - The following device(s) are recommended alternatives:

The ISL9440CEVAL1Z evaluation board is used to evaluate the performance of the ISL9440C quad-output synchronous buck controller.

The ISL9440C is a quad-output controller that integrates three PWM synchronous buck controllers and one low-dropout linear regulator controller. The ISL9440C offers programmable soft-start, independent enable functions and integrate OV/OC/OT protections. The device also offers current mode control architecture and an internal compensation network, keeping peripheral component count minimal.
