LX7180A - 4A Step-Down Regulator

Datasheet Summary

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.

Features

  • 0-4 A Step-down Regulator.
  • Ope.

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.
