Overview

The ISL85014 is a highly efficient, monolithic, synchronous buck regulator that can deliver 14A of continuous output current from a 3.8V to 18V input supply. The device uses current mode control architecture with a fast transient response and excellent loop stability. The ISL85014 integrates very low ON-resistance high-side and low-side FETs to maximize efficiency and minimize external component count. The minimum BOM and easy layout footprint are extremely friendly to space constraint systems. The operation frequency of this device can be set using the FREQ pin: 600kHz (FREQ = float) and 300kHz (FREQ = GND). The device can also be synchronized to an external clock up to 1MHz. Both high-side and low-side MOSFET current limit, along with reverse current limit, fully protects the regulator in an overcurrent event. Selectable OCP schemes can fit various applications. Other protections, such as input/output overvoltage and over-temperature, are also integrated into the device and provide required system level safety in the event of fault conditions. The ISL85014 is offered in a space saving 15 Ld 3.5mm x 3.5mm Pb-free TQFN package with great thermal performance and 0. 8mm maximum height.
