Intersil extends buck regulator portfolio

Intersil has introduced five synchronous buck regulators that step-down 12V rails to point-of load inputs as low as 0.6V for MCUs, FPGAs, memory and peripheral I/Os.

Part of the ISL850xx family of buck regulators the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 devices are able to deliver 14A, 12A, 9A and 5A of continuous output current, respectively, to industrial computers and programmable logic controllers as well as telecom, test and measurement, server and storage networking equipment.

These sync buck regulators can support input voltages of 3.8V to 18V and a wide output current range, offering designers a broad portfolio of devices with high efficiency and reliable performance. The pin compatible regulators integrate very low RDSon high side and low side MOSFETs that reduce external component count and power loss helping to extend product life. Both FETs also provide current limit and reverse current limit to boost reliability and protect the system during an overcurrent event.

Highly efficient these devices enable lower die temperatures, allowing systems to operate without cooling fans or heatsinks. Their internal compensation eliminates additional external components, which reduce design complexity and bill of materials (BOM) cost.

The ISL85014 is offered in one of the industry’s smallest 14A packages at 3.5mm x 3.5mm, freeing up valuable board space. The ISL85009 is a power efficient 9A sync buck regulator, offering high side FET RDSon at 17mΩ and low side FET RDSon of 8.5mΩ to dramatically reduce die temperatures for applications without cooling systems.

The pin-compatible ISL85014, ISL85012 and ISL85009 are able to address high load current applications, while the 5A ISL85005A and ISL85005 buck switching regulators are pin-compatible with the previously released 3A ISL85003A and ISL85003 devices.
