MagnaChip Introduces Hybrid LED Backlight Unit

MagnaChip Semiconductor Corporation, a Korea-based designer and manufacturer of analog and mixed signal semiconductor products, announced 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.
