SiLM6881 Datasheet 80v 1.0a Synchronous Step Down Regulator

Manufacturer: Sillumin

Overview: SiLM6880,SiLM6881 High Efficiency, 80V, 1.0A Synchronous Step Down Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SiLM6880/81 is a high efficiency synchronous step down regulator.

It can deliver 1A continuous current.

The SiLM6880/81 operates over a wide input voltage range from 6V to 80V and integrates the main switch and synchronous switch with very low RDSON to minimize the power loss and provide a high efficiency solution.

Key Features

  • Wide input voltage range: 6V to 80V.
  • Output current capability: 1A.
  • 1.2V reference voltage with ±1.5% accuracy over temperature.
  • Integrates low RDSON high side/ low side FET: 600mΩ/290 mΩ.
  • 20μA quiescent current and 15μA shutdown current.
  • Constant on time control for fast transient response.
  • Integrates soft start to limit inrush current.
  • Open drain power good output.
  • Programmable UVLO.
  • Peak and valley curr.
