What is a very low cost? I want something really cheap. The node between the inductor and diode is PWM switched with a fet to ground. PWM is from, say, This will produce a larger vout which can be linear regulated. Ok - here's an example: learn. The switched node can be tapped to also produce the inverted voltage via a capacitor-diode-diode charge pump.
It's all very manual though Show 5 more comments. Active Oldest Votes. The following circuit is take from an Adafruit note and shows the concept: The adafruit note isn't concerned with absolute output stability, only a range of output voltages at a pretty static output current and input voltage.
