Intersil Claims Industry's Highest Efficiency Small Footprint 6A Switching Regulator

The ISL8016 features excellent efficiency across its entire load range. It offers automatic PFM mode and operation down to 2.7V, improving efficiency and enabling extended battery life or improved Energy-Star ratings. The ISL8016 delivers efficiencies the can remain flat over the full load range, reaching as high as 97%. In addition, by switching at frequencies up to 4MHz, the ISL8016 enables a smaller overall solution size -- not just by virtue of its own compact package, but by also allowing designers to use smaller external components.



Features and Specifications

The ISL8016 integrates two low on-resistance MOSFETs, and lets users adjust operating frequency from 500kHz to 4MHz. For applications requiring minimum external components, the device offers a default 1MHz operation, a fixed internal 1ms soft start and internal compensation. The device accepts a single 2.7V to 5.5V input and can operate at 100% duty cycle, allowing the user to program a wide range of output voltages from 0.6V to Vin. Fixed output versions between 1.2V and 3.3V are also available for maximum design simplicity and even smaller footprint solutions.



In addition, the device supports current-sharing with phase interleaving allowing designers to provide multiples of 6A output current with reduced Vout ripple. For applications requiring less than 6A, the ISL8016 offers reduced current limit settings to utilize smaller inductors. To complete the full feature set, the ISL8016 has 1% reference accuracy over temperature, line and load variations, and ±10% voltage margining activated by a simple logic input.
