help 3v to 12v stepup converter...

[un_leashedslash]

baka po may alam kayo nah pwede kong gawin para maconvert ko yang 3volts sa 12volts...balak ko sana gumamit ng max682 at 681 kaso hanggang 10v lang..the source is 3v solar panel from casio calculator...

it would not have enough power to allow conversion , i fear !!

Kumusta Igan,

Ang payo ko , gamit ka ng Linear Technology :
1) Para sa design mo gamit ka ng Spcie nila
http://www.linear.com/designtools/software/ltspice.jsp
2) Para sa piling product -Buck boost(DC-DC):inductor less charge pump
at para sa pag pipilian mong parameters:

3) Meron naman silang distributor saatin, kung minsan nagbibigay pa ng libreng samples

Sige Igan , pag butihin mo ang yung desinyo.

Salamat

I agree with mvs sarma. The solar panel of a casio calculator would not have enough power to support conversion because it can supply only a few milliwatts.

bili ka na lang ng 12 volts na solar panel.. bat ka pa magpapakahirap? approx 200 peso per watt....

naku mahihirapan  ka nga  niyan.. sa sobrang  hina ngoutput  ng solar  panel  mu

Because of the Low Power source which is a solar panel,  You can use a a switched capacitor converter like the ICL7660 or MAX1044 if the load is also a lower power circuit.  You can view the datasheet in www.maxim-ic.com using the IC in Doubler mode and cascade it to generate the 12V output you needed. I hope this helps.
