L6981 Synchronous Step-Down Converter

STMicroelectronics' synchronous monolithic step-down regulator is capable of delivering up to 1.5 ADC to the load

Image of STMicroelectronics L6981 Synchronous Step-Down ConverterSTMicroelectronics' L6981 is an easy to use synchronous monolithic step-down regulator capable of delivering up to 1.5 ADC to the load. The wide input voltage range makes the device suitable for a broad range of applications.

Housed in SO8 package, the L6981 is available both in low consumption mode (LCM) and low noise mode (LNM) versions. LCM maximizes the efficiency at light-load with controlled output voltage ripple so the device is suitable for battery-powered applications. LNM makes the switching frequency constant and minimizes the output voltage ripple for lightload operations, meeting the specification for low noise sensitive applications.

Features
  • 3.5 V to 38 V operating input voltage
  • Output voltage from 0.85 V to VIN
  • 1.5 ADC output current
  • Internal compensation network
  • Two different versions: LCM for high efficiency at light-loads and LNM for noise sensitive applications
  • 2 μA shutdown current
  • Overvoltage protection
  • Output voltage sequencing
  • Thermal protection
  • Synchronization to external clock for LNM devices
  • SO8 package
