Featuring small size, long battery life, and low power consumption, LEDs are expected to be used in a variety of new applications as a next-generation lighting source. With remarkable improvements in ...

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 ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...

Phihong USA has developed a new constant-current external LED driver for high power applications, including street and parking area lighting. Phihong USA has developed a new constant-current external ...

Typical uses today include backlighting for LCD TVs, projectors, computer displays, camera flashes, and vehicle brake lights. All need constant-current LED drivers that are economical and offer high ...

As high-efficiency ultra-bright white LEDs come down in cost, they are approaching cost parity with conventional mercury vapour, HID quartz metal halide and high/low pressure sodium lighting on a cost ...

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 ...
