Product Overview

STEVAL-L7983ADJ step-down switching power supply evaluation board is based on the L7983PUR regulator in an DFN10 3x3mm package with 12V set output voltage. The selected switching frequency is 1MHz and it can be adjusted by applying an external clock on the LNM/LCM pin or by changing the frequency programming resistor. The step-down monolithic switching regulator can deliver up to 300mA DC based on peak current mode architecture. The wide input voltage range and adjustable UVLO threshold meet the specification for 12V, 24V and 48V industrial bus standards. L7983 supports dynamic Low Consumption Mode (LCM) to Low Noise Mode (LNM) transition. LCM is designed for applications with active idle mode to maximize the efficiency at light load with controlled output voltage ripple, while LNM keeps the switching frequency constant over the load current range for low noise applications.
  • Internal soft-start
  • Synchronization to external clock
  • Internal compensation network
  • Auto recovery overcurrent, overvoltage and thermal protection
