VR13/IMVP8 PWM Controller
ISL69128 Features The ISL69128 is a digital dual output, flexible multiphase
(X+Y ≤ 7) PWM controller designed to be compliant with Intel
VR13 and IMVP8 specifications. The digital multiphase
controller can be configured to support any desired phase
assignments up to a maximum of seven phases across the two
outputs (X and Y). For example, 6+1, 5+2, 4+2, 3+3, 3+2, or
even single output operation as a 7+0 configuration are
supported. ISL69128, with a flexible X+Y ≤ 7 phase
assignment, supports SVID interface along with PMBus 1.3
specifications, making it ideal for controlling the
microprocessor core, memory, and system rails per Intel VR13
or IMVP8 platforms. Advanced linear digital modulation scheme
-Zero latency synthetic current control for excellent HF
current balance
-Auto phase add/drop with a boot refresh function for
excellent load vs efficiency profile
-Dual edge modulation for faster transient response
-Excellent DVID performance The ISL69128 utilizes Intersil’s proprietary digital linear
synthetic current modulation scheme to achieve the industry’s
best combination of transient response and ease of tuning …
