Mar 17, 2017 14A, 3.8V to 18V Input, Synchronous Buck Regulator
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. Features 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. Prebias start-up, fixed 3ms soft-start Power input voltage range variable 3.8V to 18V PWM output voltage adjustable from 0.6V Up to 14A output load Selectable fSW of 300kHz, 600kHz, and external
synchronization up to 1MHz Peak current mode control
-DCM/CCM
-Thermally compensated current limit
-Internal/external compensation 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 …
