Santa Clara, Calif. — National Semiconductor Corp. says it has introduced the industry's first common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation ...
How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...
Linear Technology announces the LT3761, a 60V DC/DC controller designed to operate as a constant-current source and constant-voltage regulator. Its internal PWM dimming generator makes it ideal for ...
A matrix of eight switches form an eight-channel LED bypass switching IC that controls on/off/dimming and fault indications for an LED array. In operation, the switch matrix interfaces with an ...
The LT3796-1 is a switching controller designed to regulate a constant current or constant voltage at the output—necessary requirements for driving LEDs. It uniquely features two independent current ...
To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.
KP1601X is a high efficiency Buck LED power switch designed for LED backlight. It adopts quasi-resonant control mode and integrates accurate zero-crossing detection of inductor current, which can work ...
