Hello,

I'm not sure if this is OT, so I put it here to be sure.

I am looking for an IC with 3 or 4 hardware pulse width modulators, with
any kind of interface (I2C, SPI, etc).  My current project is to make
accent lights for my apartment using red/blue/green + white LEDs.  I
didn't see any PICs with 4 PWMs, but I have found some almost suitable
solutions:

Phillips makes the PCA 9530/1/2/3, an I2C LED dimmer with 2 to 16 bit I/O
- though each model has only two PWMs total.  Also, the SO form parts
don't seem to actually be purchasable.

The MAX 7313/4/5/6 are similar, though they have PWM on each I/O bit. 
This IC, however, has only 16 preset PWM steps, and comes only in QFN/QSOP
packages.

Is anyone familiar with an IC that might work? Something with 3 or 4 PWMs
in SO/DIP would be ideal, it doesn't need to drive the LEDs directly like
the chips above.

Thank you,

Ian
