Default Microboost heatsinking

Gotta question for any folks who happen to know...which components on the Micro-boost drivers from lava would benefit from heatsinking. I see a 8 pin chip, and another transistor looking thing, the rest are resistors, caps, and a diode...now the inductor i know doesnt need it, but im looking to run 500mA with NO duty cycle as in constant on for as long as i like...dont worry about the diode...its sinked well, im just worried about the driver.

Any help is appreciated!

EDIT: also, i was wondering if anyone had definite pictures showing the solder bridges that allows you to hit 1.3A.

the IC's? well one i know is a 8-pin IC that probably does the boost fuction...and I think the other chip is a transistor that drives the current...

ok im a moron...i just figured it out for myself... thanks bluuray for spurring up my memory... its the transistor that needs the sinking... well anyways though I still would like to know whats the solder blob configuration that allows me to hit 1.2A -1.3A.
