Regulator is industry’s most efficient claims Intersil
1 min read
Described as the industry's most compact and efficient 6A synchronous buck (step down) regulator, Intersil has unveiled the ISL8016, designed for applications such as industrial automation, communications infrastructure equipment, consumer electronics and instrumentation.
According to the power management specialist, the new regulator features efficiency up to 97% and switching frequency up to 4MHz. It offers automatic PFM mode and operation down to 2.7V, and, says Intersil, delivers efficiencies that can remain flat over the full load range, reaching as high as 97%.
The ISL8016 integrates two low on resistance mosfets and has an adjustable 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 2.7 to 5.5V input and can operate at 100% duty cycle, allowing users to programme a range of output voltages from 0.6V to Vin. Fixed output versions between 1.2 and 3.3V are also available.
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 utilise smaller inductors.
