ISL68223 Digital Dual Output, 4-Phase PWM Controller Datasheet
The ISL68223 uses the Renesas proprietary 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™ software 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.
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 4 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 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)
