LX7180A-21CLQ-TR規(guī)格書詳情

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 over-current conditions. Hiccup mode provides protection for heavy over-load or short-circuit faults. Thermal protection shuts down the regulator under over-temperature 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.
