April 6, 2017 – Intersil 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. The newest members of the ISL850xx family consist of the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators. They 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.
The ISL850xx sync buck regulators support input voltage of 3.8V to 18V and output current range, offering designers a complete portfolio of device. The pin compatible regulators integrate low RDSon high side and low side MOSFETs that reduce external component count and power loss 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. The ISL850xx devices enable lower die temperatures, allowing systems to operate without cooling fans or heatsinks.
The ISL85014 is offered in a 14A packages at 3.5mm x 3.5mm. The ISL85009 offers high side FET RDSon at 17mΩ and low side FET RDSon of 8.5mΩ to reduce die temperatures for applications without cooling systems.
The pin-compatible ISL85014, ISL85012 and ISL85009 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.
