16-string White & RGB LED Drivers with Adaptive Power

Control, E²PROM, and SPI/I²C/SMBus Serial Interface

Key Features

Application Circuit

• 12-bit PWM String Dimming Operates at 240Hz

• Fast Serial Interfaces Support up to 16 Devices

per Bus:

- MSL3164 20 MHz SPI

- MSL3163 1 MHz I2C

• 8-bit Adaptive Power Correction Maximizes

Efficiency of up to Three String Power Supplies

• Drives 16 Parallel LED Strings of 10 White LEDs

Each for up to 2560 White LEDs per Serial Bus

• Supports Adaptive, Real-time Area Dimming for

Highest Dynamic Range LCD TVs and Monitors

• Programmable String Phase Reduces Motion Blur

• Global Intensity Control via Serial Interface

• 100mA Peak, 60mA Average LED String Current

• Single Resistor Sets Peak Current for all LED Strings

• ±3% Current Accuracy and Current Balance

• Video Frame (VSYNC) and Line (HSYNC) Sync

Inputs

• Sync Loss Detectors Optionally Disable LED Strings

• Multiple MSL3163/4s Share String Power

Supplies and Automatically Negotiate the

Optimum Supply Voltage
