0.6/1.6 MHz Boost Converters with 22V Inrternal FET Wsitch in SOT-32 - National Semiconductor Application Note LM2731 July 2003 (app note added 7/06)
12V to 28V DC-DC Converter with LM2585 - This boost regulator is for those times when you have a 28v relay, but want to use it with a 12v source. The circuit is built around the National Semiconductor LM2585, and uses the energy stored in an inductor to boost the 12v to 28. Output voltage can be varied by adjusting the ratio of resistor values on the feedback pin. ….(design added 11/08)
2 AA Cells replace 9V Battery Extend Operating Life - DN63  Design Notes (Linear Technology) (app note added 1/06)
2-Phase Boost Converter Delivers 10W from a 3mm x 3mm DNF Package - DN354  Design Notes (Linear Technology)  (app note added 1/06)
2-Transistor Amplifier - A simple two-stage Amplifier. Use any general-purpose NPN with high gain. It will drive low impedance headphones directly. A speaker will probably require furr boost.  (added 10/05)
3 input supply powers 3.3V Portables - 04/13/95 EDN-Design Ideas: The single-ended primary-inductance converter in Fig 1 accepts input voltages ranging from 3 to more than 6V and produces a regulated 3.3V, 200-mA output. The converter accepts an input voltage from three sources: a 5V dc wall cube, a three-cell AA battery, and a lithium backup battery.....(design idea added 6/06)
3 Output TFT LCD Bias Supply with a Boost Regulator-MP1542-DN0005 - Monolithic Power Systems, Inc Design Note (added 6/06)
3.3V converter delivers 3W from Li ION battery  - 11/05/98 EDN-Design Ideas:  Lithium-ion batteries are rapidly gaining popularity in portable applications because of ir superior energy density, low self-discharge rate, and high cell voltage. When you use one Li-ion battery to power a 3.3V dc/dc converter;.....(design idea added 11/05)
3-Band Equalizer - Using a single op-amp this easy to make equalizer offers three ranges, low frequency, mid frequency, and high. With component values shown re is approximately +/-20dB of boost or cut at frequencies of 50Hz, 1kHz and 10kHz. Supply voltage may be anything from 6 to 30 Volts....(added 03/04/05)
3MHz Micropower Synchronous Boost Converters Deliver 3W from Two Cells in a Tiny MSOP Package - DN246  Design Notes (Linear Technology) (app note added 2/06)
4-Phase Monolithic Synchronous Boost Converter Delivers 2.5A with Output Disconnect in a 5mm x 5mm QFN Package - DN332  Design Notes (Linear Technology) (app note added 2/06)
500kHz 6a Monolithic Boost Converter LT1370 - DN183  Design Notes (Linear Technology) (app note added 1/06)
