ISL68124
Digital Dual Output, 4-Phase Configurable, PWM Controller with PMBus
The ISL68124 is a digital dual output, flexible multiphase
(X+Y ≤ 4) PWM controller supporting the latest PMBus 1.3
specifications. Either output can be configured to support any
desired phase assignments up to a maximum of four phases
across the two outputs (X+Y). For example, 3+1, 2+2, 2+1, or
even a single output operation as a 4+0 configuration are
supported. The ISL68124 uses Intersil’s proprietary linear
synthetic digital current modulation scheme to achieve the
industry’s best combination of transient response and ease
of tuning while addressing the challenges of modern
multiphase designs.
Device configuration and telemetry monitoring is
accomplished using Intersil's intuitive PowerNavigatorв„ў GUI.
The ISL68124 device supports on-chip nonvolatile memory to
store various configuration settings that are user selectable
through pin-strap, giving system designers increased power
density to configure and deploy multiple configurations. The
device supports an automatic phase add/drop feature to allow
maximum efficiency across all load ranges. Thresholds for
automatic phase add/drop are user programmable using the …
