Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...
This dimming controlled LED driver circuit is designed using LM3409 P-channel MosFET controller for step-down (buck) current regulators.The LM3409 devices use Constant Off-Time (COFT) control to ...
This engineering report describes an LED driver power supply that uses a member of the LinkSwitch-TN family of devices, the LNK306DN. The circuit regulates its load current to 300 mA while developing ...
