ICL 7660 ALTERNATIVE

[daverave]

lie. clear lie. higher voltage in coil (IN COIL) and (AND) the CURRENT you can get with MORE PULSE WIDTH only.

no another way.

ie if you have now 50us so if you go on 100us you get MORE TX power. but here is ONE moment...
throw out your 800mA*h batts in garbage basket. just cause you can not use SMALL RESERVE POWER batts
in HIGHT POWER EXPENSE UNIT.

for 1000us PULSE WIDTH unit you MUST use batt... look at this pic
and yes - you will get the depth. be ready also to use another power mos-fet... on another voltage
and another current.

can i mount this battery on the back of my detector

I use Findchips.com when trying to source a part. Really useful when searching ebay. Many times
ebay prices are a lot higher than Mouser or Farnell. Also data sheets are linked from the larger venders.

sourcing parts

For a single chip, the shipping is the biggest part of the cost. But you can find them.
