Auto-Adjustable Regulators Power Pentium Pr - 12/07/95 EDN Design Ideas: Powering intel’s next-generation Pentium Pro (P6) µ proves to be a nontrivial task due to both the greater-than-30W load and the need to finely adjust input voltage level on a chip-by-chip basis. The AA32A family of switching regulators from Astec America Design by Maury WrightAstec America Inc, Carlsbad, CA -- 12/07/95
Automatic Local Sensing Improves Regulation - 1/04/96 EDN Design Ideas: A power supply usually needs to provide a regulated voltage across a load, but there is always some voltage drop across the conductors that carry the current to the load. Two common techniques help the supply to achieve the proper voltage across the load. One Design by Jimmie D Felps, Hewlett-Packard Colorado Springs, CO
Automatic Trickle Charger - Scroll down to find this circuit. Here is the schematic for the automatic charger I have been using for my kids' battery cars. The charger is a small molded unit that probably doesn't supply more than an amp and this circuit would have trouble with much more. No current limit is provided by this circuit __ Contact: Charles Wenzel of Wenzel Associates, Inc.
Automotive 5V Regulator with Cold Crank Capability - The LTC3115-1 is a high voltage monolithic synchronous buck-boost DC/DC converter. its wide 2.7V to 40V input and output voltage ranges make it well suited to a wide variety of automotive and industrial applications. A proprietary low noise switching algorithm optimizes efficiency with input voltages that are above, below or even equal to the output voltage and ensures seamless transitions between operational modes. __ Linear Technology/Analog Devices App Note, Dec 5, 2011
Automotive 9V-19.5Vin to 5V at 1A with 60V Transient Protection & 1.7MHz Switching Frequency - The LT3682 is a 1A monolithic buck switching regulator that accepts input voltages from 3.6V to 36V and transients up to 60V. it features an adjustable and synchronizable switching frequency from 250kHz to 2.2MHz. it also has the ability to monitor the current flowing through the external catch diode, thus providing an extra level of protection against output fault conditions over the entire operating frequency range, regardless of input voltage__ Linear Technology/Analog Devices App Note, Jul 22, 2010

Autoranging simplifies hardware & software - 07/22/99 EDN Design Ideas: A natural approach to autoranging is to use an inverting op amp and switch in one of N feedback resistors at a time for a gain of A=-RF/RO (Figure 1). However, the inverting configuration suffers from low input impedance of Zinn=RO because the negative input is at virtual ground. Design by Dana Romero, Phonex, Midvale, UT
Autoranging True RMS-to-DC Converter - A programmable gain amplifier (LTC6910-2) and a window comparator (LTC6700-1) and some control logic creates a wide dynamic range RMS to DC converter. The comparator monitors the DC output and signals whether to increment or decrement the gain to maintain a predetermined output voltage range. Knowing the output DC voltage and the gain setting can determine the True RMS amplitude of the signal being monitored__ Linear Technology/Analog Devices App Note, Mar 16, 2010
Autoreferencing nulls out sensor errors - 24-Jan-02 EDN Design Ideas: The autoreferencing circuit in Figure 1 nulls out the error of a sensor, such as a pressure transducer, at its reference level-for example, at ambient pressure.

Autotransformer regulator inverts 12V to produce 12V - 08/01/1997 EDN Design Ideas: You can create a dc/dc regulator with an internal switching MOSFET that inverts 12V to produce an output of 200 mA at 12V. The IC is a high-efficiency device whose low quiescent current (120 µA maximum) is the product of a CMOS
process that limits the absolute-maximum input-to-output voltage to 21V. Design by Dana Davis
