New power model regulator ideal for driving LEDs
Analog Devices has announced the Power by Linear LTM8005 boost DC-DC µModule (power module) regulator created for driving LEDs. The device includes a DC-DC controller, power switch, Schottky diode and current sense resistor in a 9mm x 11.25mm x 2.22mm BGA package. The device runs from a 5V to 38V input voltage range and can deliver up to 1.6A of regulated current at an output voltage of up to 38V. An Inductor is external, allowing the device to simply configure in different operation modes including boost, buck-boost, buck and SEPIC topologies with a coupled inductor.
The high-reliability H-grade version guarantees operation from –40C to 150C. The wide input voltage range and 150C operation make this LED driver perfect for automotive and industrial lighting applications.
The operating frequency is alterable from 100kHz to 1MHz, and built-in spread spectrum frequency modulation enhances electromagnetic compatibility performance. The brightness of the LEDs can be controlled by the analogue CTRL pin and by PWM dimming with a range up to 3000:1. The device offers safety features such as open LED protection, output disconnect short-circuit protection, programmable input current limit, as well as, input and output current reporting.
