Positive and Negative Charge Pump Circuit In a previous article, I have shown you how you can build your own switched capacitor voltage converter circuit using the classic industry-standard LMC7660 IC. But oftentimes there are situations when you don't have a specific IC available or the cost of an additional IC is ruining the harmony of your BOM. And this is where our beloved 555 timer IC comes to rescue. That is… |

Charge Pump Circuit - Getting Higher Voltage from Low Voltage Source The situation is simple – you have a low voltage supply rail, say 3.3V, and you want to power something that needs 5V. This is a tough call, especially if batteries are involved. The only apparent way is a switch mode converter, more specifically a boost converter. This is where we hit a roadblock – boost converters are inefficient at low powers,… |

Voltage Multipliers Voltage Multipliers are the circuits where we get very high DC voltage from the Low AC voltage supply, a voltage multiplier circuit generates voltage in multiple of peak input voltage of AC, like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output, in case of Voltage Tripler circuit. Multimeter only reads the RMS (root mean voltage) value… |
