**How to use the WS2801 LED PWM chip with MOSFETs to expand its current and voltage useage. **

The WS2801 is an interesting chip. It is a constant current LED driver with 3 drivers that the current can be set individually. This lends the WS2801 to be useful when driving RGB LEDs. Each channel runs off an internal 8-bit PWM (total 24-bits) that is serially clocked in over a 2-wire (data and clock) scheme. This gives each channel 256 levels of brightness. The WS2801 can also be chained together with other WS2801 chips to reduce I/O usage.
