General Description

The VAS6685 is a 18-channel SPI-bus to PWM converter optimized for RGB color LED lighting applications. Each channel is independently programmable for a PWM duty cycle in programable steps(4096 to 65536 steps), synchronizing with the SYNCB signal by setting a group of registers.Each output has 10mA sink/source capability and has the same PWMfrequency. The VAS6685 operates with a supply voltage range of 2.7V to 5.5V. 

VAS6685 is available in a QFN4*4-28 package.
