Onsemi CAV4201TD-GT3 | Demoboard ONSEC-18-030

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.
