Shunt Burn Issue
I've this schematic, where I'm blinking output bulbs (21W @ 12VDC). Rate of blinking is 85 counts/min. The wave comes to be of 700ms. On time 350ms.
In this 350ms of On time, initially I skip 50~100ms ...

Does a Microcontroller act as a Capacitive load or resistive?
I'm designing a unity gain buffer (IC MCP6002) and in the datasheet, it says that a small series resistor is required at the output, if the load is capacitive and is >100pF.
The input of the buffer ...

Where does the current in a Dickson Charge Pump come from? Does the oscillator/PWM pin of a microcontroller also source current?
Well, I am making a small circuit which looks like this:
When simulated, the load current gets up to about 200-280 mA no problem, so I want to implement this circuit in real life. My only problem is,...
