Five synchronous buck regulators that step-down 12V rails to PoL (point of load) inputs down to 0.6V for microcontrollers, FPGAs, memory and peripheral I/Os.

The additional members of the ISL850xx family are the ISL85014, ISL85012, ISL85009, ISL85005A and ISL85005 buck regulators. They deliver 14, 12, 9.0 and 5.0A of continuous output current to industrial computers and programmable logic controllers (PLCs) as well as telecomms, test and measurement, server and storage networking equipment.

The ISL850xx sync buck regulators support input voltage of 3.8 to 18V and wide output current range. The pin-compatible regulators integrate very low RDSon high side and low side MOSFETs that reduce external component count and power loss. Both FETs also provide current limit and reverse current limit to boost reliability and protect the system during an over-current event. The ISL850xx devices enable lower die temperatures, allowing systems to operate without cooling fans or heatsinks, says the company. Internal compensation eliminates additional external components, which reduce design complexity and bill of materials cost.

The 14A ISL85014 is offered in a 3.5 x 3.5mm package, to free up board space. The ISL85009 is a 9A sync buck regulators, offering 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, the 5A ISL85005A and ISL85005 buck switching regulators are pin-compatible with the previously released 3A ISL85003A and ISL85003 devices.

The ISL850xx 12V sync buck regulators are available now in 12-lead DFN and 15-lead TQFN packages.
