Multi-Purpose Precision Multiphase PWM Controller Evaluation Board


The ISL6558EVAL2 is a low-profile, 5V/12V input, 500kHz, and 90% efficiency DC/DC converter evaluation board. It is used to evaluate the ISL6558 multi-purpose precision multiphase PWM controller with optional active voltage positioning. The evaluation board can be pushed up to 80A in four-phase operation, or modified for 12V input applications by replacing the input capacitors with higher voltage rating capacitors.
