LD8105 - Constant Voltage and Constant Current Controller

Datasheet Summary

Description

The LD8105 is built-in with a high-accuracy 1.2V voltage reference, two op-amps and a low-side current sensing circuit in a SOT-26 package.

It provides a highly integrated solution for CV (constant voltage) and CC (constant current) dual control.

Features

  • Internal Precision ±1% Voltage Reference.
  • Secondary-side Constant Voltage and Constant Current Control.
  • Low Quiescent consumption.
  • Wide VCC operating range 3V to 38V.
  • Max. 40V voltage rating.
  • Low external component count.
  • SOT-26 Package.
