Rev.2.00
May 26, 2017 Digital Dual Output 4-Phase AMD PWM Controller
The ISL69144 is a digital dual output, multiphase PWM
controller designed to be compliant with AMD SVI2
specifications. The digital multiphase controller can be
configured to support any desired phase assignments up to a
maximum of four phases across the two outputs (X and Y). For
example, 3+1, 2+2, or even a single output operation as a 4+0
configuration are supported. With a flexible X+Y ≤ 4-phase
assignment along with PMBus and SVI2 interfaces, it is ideal
for controlling the microprocessor core, memory, and system
rails of AMD SVI2 based platforms.
The ISL69144 uses Intersil’s proprietary digital linear
predictive current modulation scheme to achieve the
industry’s best combination of transient response and ease of
tuning while addressing the challenges of powering the latest
generation of AMD microprocessors. Configuration is
accomplished through Intersil’s intuitive PowerNavigator™
GUI. Diode emulation and automatic phase add/drop features
allow the user to extract maximum efficiency from the
converter regardless of load conditions. …
