ISL68127
Digital Dual Output, 7-Phase Configurable, PWM Controller with PMBus
The ISL68127 is a digital dual output, flexible multiphase
(X+Y ≤ 7) PWM controller supporting the latest PMBus 1.3
specifications. Either of the outputs can be configured to
support any desired phase assignments up to a maximum of
seven phases across the two outputs (X+Y). For example, 6+1,
5+2, 4+2, 3+3, 3+2, or even a single output operation as a
7+0 configuration are supported. The ISL68127 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 PowerNavigator GUI. The
ISL68127 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 …
