Description

  • Typical Application for the LX7180A is a 4A step-down regulator with integrated MOSFETs. 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 to 1.195 V through a high speed (up to 3.4 MHz), bi-directional I2C bus. The LX7180 operates from 3 to 5.5 V rails and outputs 0.6V to 100% of the input voltage
