5V Regulator Cap for 9V battery

David Cook built a 5V regulator to sit atop a 9V battery:

For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not add a convenient 5V regulator cap to the collection? There are nicer ones on the market that have surface mount components, but half the fun of an electronics hobby is creating something basic in your own style. This double-decker board with flashing LED power indicator allowed me to experiment with flush battery snaps and board interconnects.

1.2V-32V @3A Variable Switching Regulator using LM317

The circuit presented here is based on LM317. Generally, LM317 is known as a linear regulator IC, but here the circuit operates as a switching regulator. This circuit operates by transferring energy
from the input to the output by using a solid state switch. Power Efficiency of a switching regulator is much higher than the linear regulators. The input voltage for this circuit is 8V-35V and it can produce the output of 1.8V to 32V, that can be varied by using potentiometer R3.

Features

  • Input(V): 8VDC to 35VDC
  • Output(V): 1.8VDC to 32VDC
  • Output load: 3A
  • PCB:68mm X 50mm

PWM POWER REGULATOR

In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the electrolyte. Because the load is purely resistive the simplest solution is a small PWM (Pulse Width Modulation) regulator. So I decided to make my own.

Buck regulators accept up to 40-V input

by Susan Nordyk @ edn.com:

A wide input range of 4.5 V to 40 V enables the TS3004x series of DC/DC synchronous buck regulators from Semtech to work in a wide range of applications, including industrial, telecommunication, and consumer. The current-mode TS30041 and TS30042 furnish 1 mA and 2 mA of continuous output current, respectively, and include integrated power switches and robust fault protection in a small 3×3-mm, 16-lead QFN package.

Configurable as quad, triple, dual or single output, the LTM4643 quad output step-down µModule [micromodule] (power module) regulator deliver, respectively, 12A, 6A & 6A or 9A & 3A, or 4 x 3A from a 9 x 15 x 1.82 mm ultrathin LGA package. by Graham Prophet @ edn.com:

This flexibility enables system designers to rely on one simple and compact µModule regulator for a variety of voltage and load current requirements in FPGA, GPU, ASIC and processor-based applications. The 1.82 mm height ultrathin package allows the LTM4643 to be mounted on the backside of the PCB, freeing space on the topside. The LTM4643 is suitable for systems with height restrictions, such as backside PCB assembly in PCIe applications and where the regulator must fit under a common heat sink or cold plate to cool high power FPGAs, GPUs, ASICs and processors in applications such as embedded computing, data storage, medical imaging and industrial systems

Housed in a 15×9×2.42-mm over-molded BGA package, the LTM8049 µModule dual-output DC/DC converter from Linear Technology is configurable for a combination of SEPIC and/or inverting operation by simply grounding the appropriate output rail. All that is needed to complete the design are input and output capacitors and a few resistors—a total of 7 components compared to approximately 30 components for a comparable discrete design.

LTC3126 is a 2.5A, 2.4V to 42V input, synchronous step-down switching regulator with integrated dual input PowerPath control. Its power stage topology enables operation from either of two independent power sources, with seamless, internally controlled transitions between inputs to ensure a stable output voltage during hot-plug and power source disconnect events.

LTC3623 – Switching regulator doubles as Class-D audio amplifier

20160822150557_ltc3623-2

Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier.

Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a reproducible way and without making things overly complex requires some serious head scratching. The anxiety may be reduced vastly though by a new adjustable synchronous buck regulator which uses a single resistor to set its output voltage anywhere between 0 and 14.5 volts. Using the device is very simple; you can even use it as an audio amplifier.
