1. The schematic in Figure 1 shows a way to increase the power available from a current-limited 5 V supply by adding power from a 5 V supply. The dc/dc converter generates a single 12 V, 150-mA (1.8 W) output from two regulated and current-limited ...

2. Low-voltage microcontrollers generally have been powered from a regulated supply, such as 1.8 to .6 V, and have very low current consumption, typically between 1 mA and 5 mA. Achieving an inexpensive, space-saving solution for effective conversion ...

1. Various switching regulator circuits exist to provide positive- to-negative conversion. Unfortunately, most controllers cannot sense the negative output directly; they require a positive feedback signal derived from the negative output. This ...

2. Before proceeding any further, the reader is warned that caution must be used in the construction, testing and use of this circuit. High voltage, lethal potentials are present in this circuit. Extreme caution must be used in working with, and ...

3. Recently available visible lasers can be operated from 1.5 V supplies, given appropriate drive circuits. Because these lasers are exceptionally sensitive to overdrive, power to the laser must be carefully controlled lest it be damaged. ...

4. The conventional way to produce dual (positive and negative) outputs from a single positive input is to use a transformer. Although such designs are relatively simple, the transformer inherently introduces the problem of size. It can be challenging ...

5. When you face the task of generating a regulated voltage that's higher than the available power-supply voltage, you may consider a boost regulator. Although a boost converter can in theory generate almost any voltage that's higher than its ...

6. Power-supply designers can choose from a plethora of available positive buck regulators that can also serve as negative boost DC/DC converters. Some buck regulators have a negative-feedback reference voltage expressly for this purpose, but ICs that ...

7. Most of today’s microcontrollers are powered with a DC voltage of 3.3 V or less. Batteries are involved for low-power embedded systems that have intermittent uses. For permanent usage, designs usually include a mains supply (with transformer ...

8. In dc/dc-converter applications in which the input voltage may be lower or higher than the output voltage, you can use either a flyback converter or a SEPIC (single-ended-primary-inductor converter). SEPICs offer lower input-current ripple and ...
