A single pulse-width modulation (PWM) input controls the PWM period and duty cycle for all strings.
These devices address the direct backlight LCD panels and monitor applications.The LED Drivers Solutions with External DC-DC and NFETs drivers family also offers the Efficiency Optimizer technology, but uses external current Basket Summary Basket Contains Scheduled Items Mfr. US Dollars USD is accepted in all countries. LED current is also digitally controlled for all eight LED strings.
The MSLB9061 board has 6 channels, each driving up to 12 series-connected LEDs at up to 30mA per channel. Digital (PWM) dimming is available through an external signal or by using the internal PWM generator via the serial interface. String current can also be controlled with an ambient light sensor (ALS) and/or a negative temperature coefficient (NTC) thermistor based temperature sensor to modulate the string output intensity. The LED drivers incorporate functionality for dynamic white point-setting, color-mixing and brightness control, as well as correlated color temperature (CCT) compensation.
Multiple MSL2040s cascade to automatically negotiate the optimum power supply voltage when driving more than four strings from a single power supply.

These devices also offer automatic fault management of string open-circuit, short-circuit and over-temperature conditions. LED Driver Basics The characteristics of light emitting diodes and an introduction to Microchip's LED drivers and how LED dimming is implemented. Patented Atmel Adaptive Power Scaling technology also delivers significant power savings.
LED dimming is achieved through an external PWM signal or an internal 8-bit PWM engine. Comprehensive monitoring adjusts for aging, faults, and thermal effects. Faults are alerted on the FLTB pin, and fault status is optionally available through the I2C/SMBus compatible serial interface. A unique combination of peak current control and pulse width dimming management offers simple full-screen brightness control, versatile area dimming, and a consistent white point.
