Which is the cheap driver (May be a LED controller module)having more outputs than TLC594 available in the market.I have to control SMD 3V LEDS.

Probably a good idea to say something more about the LEDs such as current rating or power rating, voltage drop and how many LEDs you need to have in each string and the number of strings.

i am using SMD LEDs having a supplyVoltage of 3v so that i can use a coin cell as a power source.The number of LEDs are between 40 to 50.

Have you looked at these? Each board can drive 16, and the boards are addressable for 32 boards total.

They are available on Ebay for under $5 each. Then you can have individual LED control.
Another way is to use addressable LEDs. Look for "WS2812" LEDs or LED strips.
And as mentioned above, you will have to aim a lot higher than a coin cell to power it all. At least AA cells I reckon.
