Overview
The LX7180A is a 4A step-down regulator with integrated MOSFETs placed in a space saving QFN12 2mm x 2mm package for today’s mobile devices. It uses an ultra fast constant frequency hysteretic control method and a high switching frequency to minimize external filter components while maintaining excellent regulation. At lower currents, the switching frequency is lowered (Power Saving Mode or PSM) to optimize light load efficiency and extend battery life. The LX7180A reference voltage is programmable from 0.6V to 1.195V through a high speed (up to 3.4MHz), bi-directional I2C bus. The LX7180A operates from 3V to 5.5V rails. Cycle-by-cycle current limiting protects against over-current conditions. The LX7180A operates in hiccup mode to further enhance the robustness of the converter for heavy over-load or short-circuit faults and it automatically recovers once the fault clears. Thermal protection shuts down the regulator under over-temperature conditions. Over voltage conditions will immediately shut off the output to protect against permanent damage. |
