DESCRIPTION

· The ISL68124 is a digital dual output, flexible multiphase (X+Y ≤ 4) PWM controller supporting PMBus 1.3 specifications.

· It supports various phase configurations up to four phases across two outputs (e.g., 3+1, 2+2, 2+1, 4+0).

· Utilizes Intersil’s linear synthetic digital current modulation for superior transient response and tuning ease.

· Features on-chip nonvolatile memory for storing user-selectable configurations via pin-strap.

· Includes automatic phase add/drop for efficiency optimization across load ranges.

· Comprehensive fault management system enhances system reliability.

FEATURES

· Advanced linear digital modulation with zero latency synthetic current control.

· Auto phase add/drop for optimized efficiency across load ranges.

· PMBus 1.3 support for telemetry and fault status monitoring.

· Flexible phase configuration (4+0, 3+1, 2+2).

· Diode braking for overshoot reduction.

· Differential remote voltage sensing for ±0.5% closed-loop accuracy.

· Comprehensive fault management including overcurrent, OV/UV protection, and black box recording.

· Intuitive configuration using PowerNavigator GUI with NVM for up to 8 configurations.

APPLICATIONS

· Networking equipment.

· Telecom/datacom equipment.

· Server/storage equipment.

· Point-of-load power supply (Memory, DSP, ASIC, FPGA).
