    AM VHF (122.7mhz monopole antenna - ground plane effects

    Aircraft with composite or fabric wings and bodies rarely have adequate ground planes for their antennas. Investigating the impact of 'too little' ground plane all I've been able to find is information that relates to the radiation pattern. It appears that as the ground plane shrinks the...

    Want to Boost Current Output of LM2595 simple switcher?

    Thanks, I assumed the efficiency and switching speed would suffer, still it should be a lot better than a linear regulator, Vmax 16 V to 5Volts at 3 Amps. I'm just etching a pcb to try it with an external NPN or FET. I can always look for a 2596 if the sky falls in.

    Want to Boost Current Output of LM2595 simple switcher?

    Yes I could but I have a whole tube of LM2595's and want to use them up. Have none of the others. I'm only after 3 amps.

    Want to Boost Current Output of LM2595 simple switcher?

    The LM2595 simple switcher has a current limit of 1amp. It looks like you could boost it's current capabilities by adding either a bipolar transistor or a power mosfet to the output pin 1 , linked to +Vin and use this to drive the inductor/diode/cap output. Has anyone tried this and if so, what...
