    Battery Operated Resistive Heater Control

    The cells that are being used are 2600mAh. Space constraints limit me to 1-2 cells. There also exists the peak 10-20W requirement(the user is assumed to adjust the output to some level under this) and the heater is resistive wire so I assume I can adjust the resistance based on peak current draw...

    PNP \ NPN Transistor doesnt do what it should do

    Not necessarily, but the 386 is a particularly good choice.

    Battery Operated Resistive Heater Control

    Hi all, I was considering how best to build a lithium polymer powered heating circuit. The goal is 10-20W of peak output. Known components are 1-2 lipo cells and a resistive heating coil(resistance can be varied to best suit circuit characteristics). My first thought was a PWM controlled...
