SEOUL, SOUTH KOREA & CUPERTINO, USA: MagnaChip Semiconductor Corp., an Asia-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a 4-channel LED driver for notebook computer applications and a 6-channel LED driver for tablet PCs.
The 4-channel LED driver, MAP3105, has an input voltage range of 4V to 26V and an embedded MOSFET which can boost output voltage to as much as 45V with a switching range of 500KHz ~2MHz. MAP3105 also maximizes LED brightness by increasing input current up to 40mA per channel, while minimizing current matching to less than 2 percent per channel. MAP3105 is offered in a TQFN-16L package and is 3mm x 3mm in size.
In addition, the 6-channel LED driver, MAP3106, has an input voltage range of 5V to 24V and an embedded MOSFET which can boost output voltage to as much as 40V with a switching range of 330KHz ~1MHz. MAP3106 is offered in a QFN package and is 4mm x 4mm in size.
Operating efficiency and safety have also been enhanced through a multitude of designed-in protection functions including current overload protection, LED open/short protection, over voltage protection, open Schottky diode protection among others.
H.K. Kim, executive VP of MagnaChip's Power Solutions Division said: "We are very pleased to have launched the fully integrated 4-channel and 6-channel LED backlight driver which expands our product portfolio of drivers for notebook and tablet PCs. Our goal is to continue to deliver leading-edge products by expanding our product portfolio with the latest in advanced technologies."
