Three parts provide tenfold increase in Switcher Current - 08/22/02 EDN-Design
Ideas: Industrial-control circuits often derive their power from widely varying
sources that can exceed the 40V maximum rating of popular switching ICs. This Design
Idea presents a simple, flexible, and inexpensive buck switcher that converts an input
voltage as high as 60V to 5V at several amps. The circuit t.....(design idea added

Three-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
there is approximately +/-20dB of boost or cut at frequencies of 50Hz, 1kHz and 10kHz.
Supply voltage may be anything from 6 to 30 Volts. Maximum boost 20dB is only realized
with maximum supply voltage. (added 4/05) |

Use a MicroController to Design a Boost Converter - 03/04/04 EDN-Design Ideas:
Boost converters, like other switchers, have traditionally received their control
signals from a dedicated circuit. However, a recent trend is to integrate simple
switching-power-supply building blocks into generic devices, such as microcontrollers.
An excellent example of this concept is a.....(design idea added 1/05) |
