parallax power supply 7345ru parts PWM
My 7345 is not charging the coach batteries but does supply 12power to all accessories. The transformer, fan and relays work fine. Think i need a PWM circuit for it. Contacted PP tec support and th...

The forward voltage drop of a diode is current dependent.
At 0.1 mA bias current, the diode drop is closer to 0.5V. It doesn't take much current to influence the error amp resistor divider. My recollection is you'll get 0.4 to 0.5V increase in converter output voltage. Go ahead, build it up and see what you get.

It's silicon. Forward voltage drop is rated at 0.6v. So two in series should cap the voltage at 1.2v above max. So 15vdc. That's about perfect!
