Product Summary

The ISL6261CRZ is a single-phase buck regulator implementing lntel IMVP-6 protocol, with embedded gate drivers. The heart of the ISL6261CRZ is the patented R3 Technology, Intersil’s Robust Ripple Regulator modulator. To boost battery life, the ISL6261CRZ supports DPRSLRVR (deeper sleep) function and maximizes the efficiency via automatically changing operation modes.
