The TL5001A has only 20mA output. you will need a driver plus power switch. The 78S40 IC may be a better choice, check out this URL which is a program to design a switching power supply using this IC. You can download the program and run it in BASIC. http://www.geocities.com/russlk/basic/78s40des.txt
