i want to convert 1.5 v 150 mamp to 5 v 2 amp. Is this possible ? if possible how to make circuit of this ?
thanks.

No, it is not physically possible.
1.5V at 150mA is equal to 0.225W (P=VI).
5V at 2A is equal to 10W (P=VI).
You can't magic the missing 9.775W from thin air.
It's a bit like having a glass of water that holds 0.225 litres of water, and expecting to pour it into a 10 litre bucket and have it fill the bucket. It's just not going to happen, is it?
To get 10W out you have to have at least 10W available (not taking into account any conversion losses of course). After all:
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it can change form, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.

So you will have to either provide at least 10W (plus conversion losses) of power at some voltage and convert it to 5V - be that from 1.5V say 7A at 1.5V, or maybe 12V at 1A.
