VAS6685——18-Channel, 16bits SPI-Bus to PWM Converter
General Description
The VAS6685 is an 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 programmable 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 PWM frequency.
The VAS6685 operates with a supply voltage range of 2.7V to 5.5V.
VAS6685 is available in TSSOP-28 package.
