	I need to convert an 2.4-4.6V input into a 15V for HV programming on a chip. I also need to use this 15V to power an op amp, that has a 256 step digital pot in a voltage divider mode feeding the op amp as a voltage follower. Any and all inputs for very good parts and recommendations will be appreciated. __________________ It is better to fail in originality than to succeed in imitation.

	Are you designing the circuit/board or is this a one off. Here a link for Linear LT1073 Scroll down page to find examples of LT1073's and other dc-dc converters. Here a link for Linear LTC3450 it's close on what your looking for. They have a design link if you want to look for other options. __________________ Metal is the material, The forge is life, The anvil and hammer bring character and soul.

	I designed this simple follower with a digital pot and I can get 2mV to 13.5V. How can I get a 0V signal output when I want to. How can I achieve this. The digital pot will be controlled by a MCU. Any help and advice to improve the concept will be appreciated. __________________ It is better to fail in originality than to succeed in imitation.

	What does this have to do with designing domes? __________________ If you spend all your time looking for people and things to complain about: trust me, you will find plenty to complain about.

	Go to digikey or mouser and search for boost regulators or DC to DC converters __________________ If you spend all your time looking for people and things to complain about: trust me, you will find plenty to complain about.

	Use a boost-type DC-DC converter. Scads of 'em available in all sorts of voltages.
