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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
Some applications require an input voltage higher than the breakdown voltage of the IC supply pin. In boost converters and SEPICs (single-ended primary-inductance converters), you can separate the V IN pin of the IC from the input inductor and use ...
Many single-supply-powered applications require amplifier-output swings within 1 mV or even submillivolts of ground. Amplifier-output-saturation limitations normally preclude such operation. Figure 1. This configuration uses bootstrapping to allow ...
Electronic Design Opto-electronic systems frequently require temperature stabilization for components such as laser diodes, photodiodes, prisms, and lenses. The established method for providing stabilization is to attach a resistive temperature ...
Zhongming Ye, Analog Devices Design Note System designers are asked to produce smaller, higher efficiency power supply solutions to meet the demands of power thirsty SoCs and FPGAs across all industries. The space available for the power supply ...
