WS3215 - Step-down High Brightness LED Driver

Description

The WS3215 is a continuous conduction mode inductive step-down converter.designed for driving single or multiple series LED efficiently from a voltage source higher than the total LED chain voltage.

Features

  • Simple low parts count.
  • Wide input voltage range：8V to 40V.
  • Up to 1.5A output current.
  • Output current limit protection.
  • Over temperature protection.
  • Single pin on/off and brightness control using DC Voltage or PWM.
  • Typical 5% output current accuracy.
  • Inherent open-circuit LED protection.
  • High efficiency (up to 97% ).
  • Adjustable LED constant current.
