LX7180A 4A Step-Down Regulator Production Datasheet Description Features The LX7180A is a 4A step-down regulator with 0-4A Step-down Regulator integrated MOSFETs packaged in a space saving QFN12 Operational Input Supply Voltage Range: 2mm x 2mm for todays mobile devices. It uses an ultra 3.0V-5.5V (short durations to 6.5V) fast, constant frequency hysteretic control method to Hysteretic Control Offers Best Transient minimize external filter components while maintaining Response excellent regulation. The LX7180A reference voltage is programmable from 0.6V to 1.195V through a high PWM Switching at a Constant 1.65MHz 2 speed (up to 3.4MHz), bi-directional I C bus. Power Save Mode (PSM) can be Selected to The LX7180 operates from 3V to 5.5V rails and outputs Improve Light Load Efficiency. 0.6V to 100% of the input voltage. 100% duty ratio operation Cycle-by-cycle current limiting protects against over- Input Under Voltage and Over Voltage current conditions. Hiccup mode provides protection Protection for heavy over-load or short-circuit faults. Thermal Enable and Power Good Function protection shuts down the regulator under over- 2 I C Serial Interface at 3.4Mbps temperature conditions. Over voltage conditions will immediately shut off the output to protect against Internal soft-start permanent damage. The LX7180A automatically restarts Cycle-by-Cycle Over Current Protection when all fault conditions are cleared.
