DESCRIPTION

· The ISL68137 is a digital dual output, configurable PWM controller with AVSBus interface, supporting up to seven phases across two outputs. · It features Intersil's linear synthetic digital current modulation for optimal transient response and tuning ease. · Configuration and monitoring are facilitated through the PowerNavigator™ GUI, with on-chip nonvolatile memory for storing settings. · The device includes a comprehensive fault management system and supports automatic phase add/drop for efficiency across all load ranges.

FEATURES

· Compliant with PMBus 1.3 and AVSBus standards. · Advanced linear digital modulation with zero latency synthetic current control. · Flexible phase configuration supports various phase operations like 7+0, 6+1, 5+2, 4+3. · Diode braking for overshoot reduction and differential remote voltage sensing for ±0.5% system accuracy. · Comprehensive fault management including pulse-by-pulse phase current limiting and black box recording for faults.

APPLICATIONS

· Suitable for networking, telecom, and datacom equipment. · Ideal for server and storage equipment. · Effective for point-of-load power supply in memory, DSP, ASIC, and FPGA applications.
