Specially designed for auto LED backlit display strong solution
Worcester, Massachusetts, on July 20, 2011- 雷竞技竞猜下载Allegro MicroSystems announced two new multiple output for LCD backlight LED drive.A8502andA8514Integration of the current mode boost converter with internal current switches and multiple current.LED to fill current can be parallel, in order to achieve higher LED current.They can be in 5 V to 40 V single power supply, make the parts can withstand sudden drop in load car system.
A8502 and A8514 LED drive can be selectively control external PMOS, in the case of a failure to disconnect the input power from the system.These devices with external PMOS disconnect switch, can prevent the output short circuit and over voltage, open circuit or short circuit, open circuit or short circuit of the diode VLED pin and overheating.
Two stage by wave current limiting function can provide soft start and to prevent the occurrence of high current overload current switch inside.The equipment has high PWM switching frequency (> 2 MHZ), allowing them to run over an AM radio wavelengths.These devices also have synchronous pins, to help users in the range of 600 kHz to 2.25 MHz.
A8502KLPTR - T provide 16 pin SSOP package, A8514KLPTR - T provide 20 - needle SSOP package, both have exposed the cooling plate.Two kinds of typical equipment market for 16 weeks delivery cycle.
