Three input supply powers 3.3V portables:  04/13/95 EDN-Design Ideas / (added 6/06) 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. Unlike conventional boost regulators whose battery current continues to flow during shutdown (unless you add a cutoff switch), this circuit's output turns off fully in response to a shutdown command. And, unlike flyback-transformer regulators and combination step-up/linear regulators, Fig 1 requires no transformers. Coils L1 and L2 should be the same type and have the same value, but coupling between them isn't required. You can wind the inductors on the same core for convenience, but the circuit works equally well if they are completely separate....

Three parts provide tenfold increase in Switcher Current:  08/22/02 EDN Design Ideas  /  (added 1/05)  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 is unique in that it boosts current with almost no compromise in performance, size, or cost....

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  /  (added 1/05)  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 microcontroller that combines digital and analog circuitry and makes it easier to build simple power supp......
