Hua (Walker) Bai, Linear Technology EDN Internal operating voltages in electronic devices continue to decrease, but input-source voltages don't change. As the difference between input and output voltages increases, so does the improvement in ...
Tom Gross, Linear Technology EDN The SEPIC (single-ended, primary-inductance-converter) topology is generally a good choice for voltage regulators that must produce an on output voltage that falls in the middle of the input-voltage range, such as a ...
A conventional power supply operates only in the first quadrant; positive-voltage output and current are sourced to a load or, with a deliberately miswired output, statically in the third quadrant as a minus supply. The conventional supply cannot, ...
The LT8711 is a DC/DC controller that supports synchronous buck, boost, SEPIC and ZETA topologies, or nonsynchronous buck-boost topologies. Analog Devices offers numerous synchronous buck and boost converters and regulators, but the synchronous ...
PowerPulse Analog Devices /Powered by Linear introduced a high-voltage flyback controller that does not need an optoisolator for regulation. The LT8316 samples the output voltage from the isolated flyback waveform appearing across a third winding ...
Henry Santana Electronic Design Europe The general approach to an electronic load is to use a transistor across the input terminals so the current flows from drain (collector) to source (emitter). A resistance is effected by causing a current flow ...
Our op amp family has expanded with industry-leading speed versus supply current. The LTC6258/LTC6259/LTC6260 family (single, dual, quad) provides 1.3 MHz gain-bandwidth product at a super low 20 uA supply current, with 400 uV maximum offset ...
Tom Gross EDN It can be difficult to generate a high-voltage supply from a medium-voltage input, especially if you need a surface-mount design. It is difficult to find surface-mount components with the necessary specs, especially the transformer ...
Guy Hoover, Analog Devices Design Note 568 Attaining optimal SNR performance from an ADC isn’t just a matter of providing a low noise signal to the ADC’s input. Providing a low noise reference voltage is just as important. While ...
The traditional method of controlling the upper cutoff frequency in the basic inverting-amplifier circuit of Figure 1 is to add capacitor C in parallel with R 2 . The value of C controls the cutoff frequency. R 1 and R 2 independently establish the ...
