High-Brightness LED-Driver

This is a high-brightness LED-driver circuit. To provide a constant-voltage output we usually use DC/DC regulators. But constant-current output is the one that is needed in LED application. To provide a constant-current output, we can use this circuit. Here is the schematic diagram of high-brightness LED-driver circuit : This circuit uses R1 to sense the LED current. The TPS40211 is […]
