The ISL6261 is a single-phase buck regulator implementing lntel® IMVP-6® protocol, with embedded gate drivers.
The heart of the ISL6261 is the patented R3 Technologyâ¢, Intersilâs Robust Ripple Regulator modulator. Compared with the traditional multi-phase buck regulator, the R3 Technology⢠has faster transient response. This is due to the R3 modulator commanding variable switching frequency during a load transient.
