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) |
