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 ChargeMode™ 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 and point-of-load monitoring. Additionally, the nonvolatile memory can store the desired custom configuration and settings. A fully customizable voltage, current, and temperature protection scheme ensures safe operation for the ISL8274M under abnormal operating conditions. The device is also supported by the PowerNavigator™ software, a full digital power train development environment. The ISL8274M is available in a low profile, compact 18mmx23mmx7.5mm fully encapsulated, thermally enhanced HDA package.
