I’ve a design. I’ve 13 switch and these switches control to leds. For example when i click first button, first led will be on( likewise when i click again, it’ll be out). So microcontroller want to knows everything about it. But how can i control these leds? Because i want 36 * 3 io pins( RGB). Similarly after i want to control lightness of all leds with dimmer.
Do you have any IC hints for leds control & leds pwm controller?
There are numerous LED drivers also from STMicroelectronics, e.g. LED1202 LED1642GW etc ( see LED Array Drivers STMicroelectronics) Of course, the correct type depends on several factors, e.g. how you want to control the LEDs( I2C, SPI, etc).

Of course, the correct type depends on several factors, e.g. how you want to control the LEDs( I2C, SPI, etc). With RGB LEDs you’ll clearly only switch one LED per channel, so you should be suitable to get by with one LED driver for 5V.
