LED Backlight Unit Driver combines embedded FET with IC.

Press Release Summary:

Intended for TV and monitor applications, Model MAP3301 integrates 400 V internally dimming MOSFET with low RDS(on) of less than 2.5 Ω at VGS = 10 V. Single-channel unit can drive multiple LEDs utilizing high voltages by separating IC input voltage from boost input voltage. Housed in SOIC-15 pin package, hybrid operates from 8.5–33 V, and includes PWM and analog dimming, auto restart mode protection, programmable output over voltage protection, and programmable input line voltage protection.

MagnaChip Introduces Hybrid LED Backlight Unit Driver Combines Embedded FET with IC

SEOUL, South Korea and CUPERTINO, Calif.,  -- MagnaChip Semiconductor Corporation ("MagnaChip") (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed signal semiconductor products, announced today that it has introduced a new single channel LED backlight unit driver (BLU) combining an embedded high voltage FET with the IC. The hybrid BLU (MAP3301) is targeted for efficient TV and monitor applications.

The MAP3301 features an embedded dimming FET and components within the IC that can reduce the overall chip size by as much as 50%. This allows for design efficiency and ease of use by allowing the MAP3301 to meet the tighter space requirements of many newer and slimmer LED TV monitors.

The MAP3301 can also drive multiple LEDs utilizing high voltages by separating the IC input voltage from boost input voltage. This is done simultaneously with 250V and 400V MOSFETs with very low RDS(on). The MAP3301 also allows the user to check and verify the operational functionality of the BLU driver to the LED TV through its support of pulse width modulation (PWM) and analog dimming.

"The MAP3301 LED backlight driver is a result of MagnaChip's power design expertise combined with its advanced packaging know-how," said HK Kim, EVP and General Manager of MagnaChip's Display and Power Solutions Division. "We are committed to expanding our product portfolio and broadening our customer base with industry leading LED BLU drivers targeted for the blue chip TV display manufacturers as well as the rapidly expanding and emerging markets in China."
