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 command.

IR’s unique Adaptive Transient Algorithm (ATA), based on

proprietary non‐linear digital PWM algorithms, minimizes

output bulk capacitors and Multiple Time Programmable

(MTP) storage saves pins and enables a small package size.

Device configuration and fault parameters are easily

defined using the IR Intuitive Power Designer (IPD) GUI and

stored in on‐chip MTP.

The IR36021 provides extensive OVP, UVP, OCP and OTP

fault protection and includes thermistor based temperature

sensing with VRHOT signal.

The IR36021 includes numerous features like register

diagnostics for fast design cycles and platform

differentiation, truly simplifying VRD design and enabling

fastest time‐to‐market (TTM) with “set‐and‐forget”

methodology.
