3.3V to 30V DC/DC converter using SN6505A

Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input voltage as low as 2,5V - that makes it great for battery devices. It's also nice, that it's a very minimalist design - on primary side all what is needed is decoupling capacitor. One disadvantage is that it doesn't have ...

Simple RS232 to logic level converter for PIC microcontroller

The circuit shown will convert logic level voltages to and from RS232 serial voltages levels. For basic serial comms between a Microchip PIC and a PC or other device you generally only need to connect the Gnd, Txd and Rxd lines. This little circuit will work with a supply voltage of 3.3v to 5v making it ideal for interfacing with a PIC  It derives the negative supply for the RS232 transmit data from the ser ...

9V/1kV DC/DC converter

Currently I'm working on a device to electrocute home insects like cockroaches, progress is small because they are smarter than I thought, but that's a different story. For that project I had to find a source of sufficient high voltage and output power. Presented in previous post 5V/400V converter had insufficient voltage and power, another option, flyback transformer was too dangerous to be used here. Fina ...
