VAS6685 18路 16bits PWM 控制专业LED驱动

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 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 PWM frequency.
The VAS6685 operates with a supply voltage
range of 2.7V to 5.5V.
VAS6685 is available in TSSOP-28 package.
