Maxim Integrated
General Description
The MAX17021 evaluation kit (EV kit) demonstrates the high-power, dynamically adjustable, multiphase IMVP-6.5+ notebook CPU application circuit. This DC-DC converter steps down high-voltage batteries and/or AC adapters, generating a precision, low-voltage CPU core VCC rail.
