.. The output of IC 1 controls the gate bias applied to MOSFET Q 1 , which is normally on. When latch-up occurs, power-supply current drain rapidly increases by an order of magnitude or more. The large voltage drop developed across R 6 ...
.. which dissipate much less power. Figure 1. Obtaining feedback from a low-voltage secondary winding, this high-voltage supply generates 500 V with low quiescent current. The MAX1605 IC from Maxim contains the necessary switching ...
.. supplies. As more and more of these systemon-a-chip (SoC) ICs proliferate the marketplace, the need for particular power supply sequencing and power management issues arises. There is usually enough information in datasheets from Analog ...
.. Drew, Linear Technology LT Journal Analog circuits often need a split-voltage power supply to achieve a virtual ground at the output of an amplifier. These split-voltage power supplies are generally ...
.. can give us a higher fixed voltage. To obtain an adjustable output either from a SMPS or conventional transformer based supply, one needs to use a linear regulator or a switched mode buck converter. For a buck converter, a MOSFET or an ...
Overview The Power Analyzer is a programmable electronic constant current dummy load with two high side voltage and current sensors for an automatic analysis of power supplys, DC/DC converters, voltage regulators, batteries, chargers, power ...
Assume that a design requires positive voltage, but only a negative-voltage power source is available. Using a standard boost-converter IC in the circuit of Figure 1, you can efficiently generate a positive voltage from a negative source. The boost ...
.. these requirements and generates an AMI waveform from an NRZ input using only a few gates, a flip-flop, and a single 5 V supply. Figure 1. The NRZ to AMI converter generating bipolar pulses uses single supply. Refering to Figure 1, the ...
.. Two standard transformers, T 1 and T 2 (220 V ac to 6 V ac, 10 W), are used to make an isolated replica of the mains supply, V M . This replica is doubled and rectified using D 1 , D 2 , C 1 , and C 2 to get about 560 V at V IN from ...
.. of a positive precision voltage reference. This approach typically requires a positive reference, the op amp, and two supply rails to generate the negative output. Another approach to generate the negative supply rail uses a ...
