12V Synchronous Buck Regulator Family Delivers Up to 14A

The ISL850xx sync buck regulators support input voltages of 3.8V to 18V and wide output current range, offering designers a complete portfolio of devices with high efficiency and reliable performance. They deliver up to 14A of continuous output current to industrial computers and programmable logic controllers as well as telecom, test and measurement, server and storage networking equipment.

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 3A ISL85003A and ISL85003 devices.

These regulators integrate very 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 high efficiency ISL850xx 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.
