ISL8274M
30A/30A Dual-Channel Digital PMBus Step-Down Power Module
FN8931 Rev.1.00 Jan 4, 2018
The ISL8274M is a complete PMBus enabled DC/DC, dual-channel, step-down advance power supply, capable of delivering up to 30A per channel and optimized for high power density applications.
Operating across an input voltage range of 4.5V to 14V, the ISL8274M offers adjustable output voltages down to 0.6V and achieves up to 95.5% conversion efficiencies. A unique ChargeModeā¢ control architecture provides a single clock cycle response to an output load step and can support switching frequencies up to 1.06MHz. The power module integrates all power and most passive components and requires only a few external components to operate. A set of optional external resistors allows the user to easily configure the device for standard operation. For advanced configurations, a standard PMBus interface addresses tasks such as sequencing and fault management, as well as real-time full telemetry.
