Intersil unveils highly integrated and flexible synchronous buck regulators

Intersil Corporation has announced the ISL85410 and ISL85418 synchronous buck regulators that are intended for complex industrial and medical systems. These new regulators have been designed to efficiently down-convert the DC voltage from a power supply or battery to power multiple microprocessors and board components, at various voltage requirements.

The ISL85410/18 offer designers greater flexibility, operating over a wide range of input and output voltages, and because the devices are pin-to-pin compatible, a single layout can be leveraged across multiple systems, accelerating time to market and reducing design cost.

The ISL85410/18 synchronous buck regulators are highly integrated resulting in better efficiency while reducing the number of required external components and enabling a more compact footprint. The ISL85410/18 synchronous buck regulators integrate both the high-side and low-side field-effect transistors (FETs), eliminating the need for an inefficient low-side diode. By also eliminating the need for external compensation, the overall bill of materials (BOM) is reduced to only five external components. The minimal component count of the ISL85410/18 reduces the solution footprint size and overall space requirements for a power design, which is important for space constrained applications.

Intersil’s ISL85415 synchronous buck regulator is also pin-to-pin compatible with the ISL85410/18, and together provide system designers with a versatile down-converting solution that can be used to support a wide input voltage range from 3V to 36V with 500mA to 1A options. Designers can reuse a single proven, reliable layout for different power levels allowing for enhanced flexibility, reduced design time and accelerated time to market.

“From industrial process control to medical imaging, industrial designers are being asked to reduce design time and improve efficiency while ensuring the delivery of robust and reliable solutions,” said Colm Brazil, senior marketing manager for Intersil’s Industrial Power group. “To address the increasing complexity of industrial system designs and the proliferation of voltage rails, the ISL8541X family of synchronous buck regulators delivers an integrated, reliable and easy-to-use solution that brings flexibility, a reduced component count and improved efficiency to power designs.”
