Description

General part information

L7983 Series

The L7983 device is a step-down monolithic switching regulator able to deliver up to 300 mA DC based on peak current mode architecture.

The output voltage adjustability ranges from 0.85 V to VIN. The wide input voltage range and adjustable UVLO threshold meet the specification for the 12 V, 24 V and 48 V industrial bus standards.

The "Low Consumption Mode" (LCM) is designed for applications active during idle mode, so it maximizes the efficiency at light load with controlled output voltage ripple. The "Low Noise Mode" (LNM) makes the switching frequency constant overload current range, meeting the low noise application specification. The L7983 supports dynamic LCM to LNM transition.
