TLC5927: More than 16-channels Constatnt current LED sink Driver

Part Number:TLC5927

Dear TI,

I am using now your TLC5927 Driver but for new project I have to drive 400 LEDs and PCB need to be small. Can you please recommend an IC Driver with more than 16-channels,around 50mA pro channel, with SPI Interface and small footprint/package.

Tanks a lot
