Boost converter for 12v dc motor driving

[RAHUL_KUMAR]

i was using boost converter for running a 12v dc motor of 4000 rpm ,but within 4 second boost converter get heated . and i was not getting the desired output like 4000 rpm .
what is the reason of heating and what can be the alternative for driving 4000 rpm 12v dc motor from 5v dc input ?

Hi,

Heating has to do with dissipated power and heat sink.
Dissipated power depends on efficiency and load power (voltage and current)
Efficiency mainly depends on circuit.

Therefore:
* show your circuit
* give values to be able to calculate (at least: estimate) dissipated power.

Values like "4000 RPM" and "4 s" are not related to heating...
