IR36021 Description
The IR36021 is a dual‐loop digital multi‐phase buck controller designed for point of load applications. The IR36021 include Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. Dynamic Phase Control adds/drops active phases based upon load current and can be configured to enter 1‐phase operation and diode emulation mode automatically or by mand.
