The TLC5973 is an easy-to-use, 3-channel, 50-mA constant sink current LED driver. The single-wire, 3-Mbps serial interface (EasySet) provides a solution for minimizing wiring cost. The LED driver ...

The A6280 from Allegro MicroSystems Europe is a new 3-bit constant current LED driver which enables users to minimise the number of components needed to drive LEDs with large pixel spacing. The new ...

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

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 ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The LT3954, a DC/DC ...

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 ...
