Switching power supply.....Wich chip DIY?

[Franck]

Hi !

I am looking for a neat stup-up converter that will convert 12 to 16 volts, (to use my Sheldon charger for 3S lithium packs from 12V car battery). I have a simple chargepump right now, but am looking for a neat IC based scheme.

Can anyone help me out ?

Best regards,

Frank

There are many to choose from. I would start with Linear Technology; they have a good range of chips and good apps data. Look at linear.com; look for power/ switching regualtors/ boost controllers/ ; look for one with the specs you need. For example, the LT1619 is easy to use. The data sheet tells how to select values. Digikey.com usually has parts.

How about the Simple Switchers from National?
