LED driver
A LED driver which controls the brightness of the LED has High accuracy of 16-channel driver which delivers constant currents, 256-step brightness control and 65536-step grey scale control. The new driver can deliver output voltages of up to 38V and provide constant currents of between 2mA and 80mA per channel just using a single resistor. Both the output-to-output accuracy and IC-to-IC accuracy of the TB62721 is 1.5%. This allows large displays based on multiple LED chains and drivers to maintain consistent brightness levels within very tight tolerances. Designed for secure, reliable operation, the TB62721 features on-board protection including thermal shutdown, output open and short-circuit protection, and Power-on-Reset.
