DATASHEET ISL8274M FN8931 Rev.1.00 30A/30A Dual-Channel Digital PMBus Step-Down Power Module Jan 4, 2018 The ISL8274M is a complete PMBus enabled DC/DC, Features dual-channel, step-down advance power supply, capable Complete digital power supply of delivering up to 30A per channel and optimized for 30A/30A dual-channel output current high power density applications. 4.5V to 14V single rail input voltage Operating across an input voltage range of 4.5V to 14V, the ISL8274M offers adjustable output voltages down to Up to 95.5% efficiency 0.6V and achieves up to 95.5% conversion efficiencies. A Programmable output voltage unique ChargeMode control architecture provides a single clock cycle response to an output load step and can 0.6V to 5V output voltage settings support switching frequencies up to 1.06MHz. The power 1.2% accuracy over line/load/temperature module integrates all power and most passive components ChargeMode control loop architecture and requires only a few external components to operate. A set of optional external resistors allows the user to easily 296kHz to 1.06MHz fixed switching frequency configure the device for standard operation. For advanced operations configurations, a standard PMBus interface addresses No compensation required tasks such as sequencing and fault management, as well as real-time full telemetry and point-of-load monitoring. Fast single clock cycle transient response Additionally, the nonvolatile memory can store the desired PMBus interface and/or pin-strap mode custom configuration and settings. Fully programmable through PMBus A fully customizable voltage, current, and temperature Pin-strap mode for standard settings protection scheme ensures safe operation for the ISL8274M under abnormal operating conditions. The device is also Real-time telemetry for V , V , I , IN OUT OUT supported by the PowerNavigator software, a full digital temperature, duty cycle, and f SW power train development environment.
