Overview

4A Step-Down Regulator LX7180A Description The LX7180A is a 4A step-down regulator with integrated MOSFETs packaged in a space saving QFN12 2 mm x 2 mm for today’s mobile devices.
It uses an ultra-fast, constant frequency hysteretic control method to minimize external filter components while maintaining excellent regulation.
The LX7180A reference voltage is programmable from 0.
6 V to 1.
195 V through a high speed (up to 3.
4 MHz), bi-directional I2C bus.
The LX7180 operates from 3 V to 5.
5 V rails and outputs 0.
6 V to 100% of the input voltage.
Cycle-by-cycle current limiting protects against overcurrent conditions.
Hiccup mode provides protection for heavy over-load or short-circuit faults.
Thermal protection shuts down the regulator under overtemperature conditions.
Over voltage conditions will immediately shut off the output to protect against permanent damage.
The LX7180A automatically restarts when all fault conditions are cleared.
