Overview

TopologyBuck Converter
Switching frequency1000 kHz

Description

The CAV4201 is a high efficiency step−down converter optimized to drive high current LEDs. A patented switching control algorithm allows highly efficient and accurate LED current regulation. A single RSET resistor sets the full scale LED string current up to 350 mA from supplies as high as 36 V. The switching architecture of the CAV4201 results in extremely low internal power dissipation allowing the device to be housed in a tiny package without the need for dedicated heat sinking. The device is compatible with switching frequencies of up to 1 MHz, making it ideal for applications requiring small footprint and low value external inductors. Enable, analog dimming and LED shutdown control is provided via a single input pin, CTRL. Additional features include overload current protection and thermal shutdown. The device is available in the low profile 5−lead thin SOT23 package and is ideal for space constrained applications.

Features

  • LED Drive Current up to 350 mA
  • Compatible with 12 V and 24 V Standard Systems
  • Handles Transients up to 40 V
  • Single Pin Control and Dimming Function
  • Power Efficiency up to 94%
  • Drives LED Strings of up to 32 V
  • Open and Short LED Protection
  • Parallel Configuration for Higher Output Current
  • CAV Prefix for Automotive and Other Applications requiring Site and Change Control
  • TSOT−23 5−lead Package
  • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

Typical applications

  • 12 V and 24 V Lighting Systems, Automotive and Aircraft Lighting, General Lighting, High Brightness 350 mA LEDs
