About Portable adjustable power supply design
This paper presents the design of a portable, multiple-output, adjustable DC power supply based on synchronous Buck and Buck-Boost converter topologies. Powered by a Li-ion battery pack (two batteries in series), the system delivers four distinct DC voltages: 3.3V, 5V, 12V, and −12V.

6 FAQs about [Portable adjustable power supply design]
What is an adjustable DC power supply?
An adjustable DC power supply is a mainstay of the electrical and electronics laboratory. It is indispensible in the prototyping of electronic circuits and extremely useful when examining the operation of DC systems. The handheld digital multimeter or DMM is also important.
What is an adjustable / programmable power supply?
An adjustable / programmable power supply is a device that allows digital or analog control of the power supply output by a control system for maximum versatility. The control system can control and monitor the power supply output voltage and current from virtually anywhere there is an Ethernet connection.
Do you need an adjustable power supply?
Everyone sometimes needs an adjustable power supply. Bench power supplies are expensive and therefore we usually use what's available. The most well known power supplies of a high current low voltage are AT or ATX supplies from computers.
What is an adjustable output power supply (AVS)?
Using AVS allows the processor to optimize the core voltage, thus improving performance and reducing power dissipation. This is just one example of how to create an adjustable-output power supply. For more information, see my latest Power Tips post on EETimes.
How do you adjust the output voltage of a power supply?
The output voltage of a power supply is usually a fixed voltage, but sometimes it may be necessary to adjust that output voltage. For example, you may be able to reduce the power dissipation in a low-voltage high-current processor – while still keeping performance high – by adjusting the voltage fed to the core.
Can a monolithic CMOS DC power supply meet a hand-held device?
A monolithic CMOS DC power supply could meet the severe size and efficiency requirements of a hand-held device. This chapter describes a design methodology for such converters. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
