Digital, Dual Output, 7-Phase Configurable, VR13/IMVP8 PWM Controller FN8914
Rev.1.00
May 25, 2017 The ISL69138 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. The ISL69138, with a flexible X+Y ≤
7 phase assignment, supports the 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.
The ISL69138 uses Intersil’s proprietary digital, linear, synthetic, 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 Intel microprocessors. Device configuration and monitoring are accomplished using Intersil’s intuitive
PowerNavigatorв„ў GUI. Diode emulation and automatic phase add/drop features allow the user to extract maximum
efficiency from the converter regardless of load conditions.
The ISL69138 supports a comprehensive fault management system to enable the design of highly reliable systems.
From a multi-tiered overcurrent protection scheme to the configurable power-good and catastrophic fault protection
flags, almost any need is accommodated.
With minimal external components, easy configuration, robust fault management, and highly accurate regulation
capability, implementing a high-performance, multiphase regulator has never been easier. Features 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 Dynamic Voltage Identification (DVID) performance Flexible phase assignment from 0 to 7 phases per output Up to 1MHz switching frequency operation for high density designs Diode braking for overshoot reduction Diode emulation for enhanced light-load efficiency Differential remote voltage sensing supports В±0.5% closed-loop system accuracy over load, line, and temperature Highly accurate current sensing for excellent load line regulation and accurate OCP Supports ISL99227 60A …
