Hi guys,
I have non-inverting digital amplifier/switch using an npn-pnp pair of transistors. Now this circuits works perfectly fine. But as soon as the vcc coming out of pnp is fed to boost converter IC, the VCC at pnp drops to .5v volts ? As if pnp is turn off ?
I am guessing this is due to pnp fails to provide enough current for boost converter IC ? your thoughts are welcome.
