Microsemi expands backlight controller line

Microsemi's LX6502 full-bridge controller integrates 12V gate drivers with 800mA source/1000mA sink drive. It employs its patented third-generation PureBLACK mega-contrast dimming technology, which provides high image quality with improved black levels and increased dynamic contrast.

Microsemi's LX6502 inverter supports full-bridge, high- and low-side N-channel power MOSFET configurations with input voltages to 35V. An integrated on-chip voltage regulator with under-voltage lockout protection further minimizes the overall system BOM costs.

Additional BOM cost reductions are enabled by a fully integrated suite of protection functions that include soft-start, direct duty cycle control with maximum duty limiting, and over-current and over-voltage protection.

Additional features include inverter SYNC functionality; PWM or analog-based burst dimming; a wide range of supply operation from 10V to 35V; and a -40°C to +85°C operating temperature range. The LX6502 is offered in a 28-lead, wide-body small outline (SOIC) plastic package.

Pricing: Less than $0.64 each in OEM quantities.
Availability: Production samples are available now; volume production is scheduled to begin in April 2010.
