1 / 97 page  FN9297 Rev.1.00 Page 1 of 96 Oct.1.20 ISL68224 Digital Triple Output, 6-Phase PWM Controller Datasheet The ISL68224 is a digital triple output multiphase (X+Y+Z ≤ 6) PWM controller with PMBus V1.3 compatibility. The controller can be configured to support any phase assignment up to a maximum of six phases across the three outputs (X, Y, and Z). For example, 4+1+1, 3+2+1, 5+1+0, 2+2+2, or even a single output operation as a 6+0 configuration is supported. When combined with the Renesas family of Smart Power Stages and DrMOS devices, designs of exceptional density and performance can be created. The ISL68224 uses the proprietary Renesas digital synthetic current modulation scheme to achieve the industry-best combination of transient response, ease of tuning, and efficiency across the full load range. Diode emulation and automatic phase add/drop features allow you to extract maximum efficiency from the converter regardless of load conditions. You can use the intuitive Renesas PowerNavigator™ to configure and monitor the device. With minimal external components, easy configuration, robust fault management, and highly accurate regulation capability, implementing a high-performance, multiphase regulator has never been easier. Applications • DDR memory solutions • Artificial intelligence/accelerator cards (FPGA, ASIC) • Network equipment • Server/storage equipment • Telecom/datacom equipment • Point-of-Load (POL) power supply (memory, DSP, ASIC, FPGA) Related Literature For a full list of related documents, visit our website: • ISL68224 device page Features • Advanced linear digital modulation scheme ○ Auto phase add/drop with PFM mode for excellent load vs efficiency profile ○ Dual edge modulation with optional diode braking for faster transient response ○ Excellent VOUT transition performance ○ Zero latency synthetic current control for excellent high frequency current balance • Flexible phase assignment from 0 to 6 phases per output • Up to 2MHz switching frequency operation for high density designs • Differential remote voltage sensing supports ±0.5% closed-loop system accuracy over load, line, and temperature • Highly accurate current sensing for excellent load-line regulation and accurate OCP ○ Supports the full range of the Renesas Smart Power Stage (SPS) devices • Comprehensive fault management enables high reliability systems ○ Pulse-by-pulse (per phase) and total output current limiting ○ Black Box status recording capability with first fault indicator • Intuitive configuration using PowerNavigator • SMBus/PMBus V1.3 compatible • Up to 16 user configurations stored in device Non-Volatile Memory (NVM) |
