Introduction Flyback power converters are currently some of the most common converter topologies around. This is due to the simplicity of their design and the competitive size/cost/efficiency ratio their can deliver, especially in the mid-level ...

EMI is a plague upon power electronic design architectures, and it can be mitigated in numerous ways. Adding an EMI filter may seem like the most obvious choice, but there may be a better first step. Modern electronic power system architectures are ...

Introduction The high dv/dt and di/dt switching transients during MOSFET commutation are the chief sources of both conducted and radiated EMI from switching DC/DC regulators. While the optimization of PCB layout for gallium-nitride (GaN) switching ...

For containing large amounts of bulk capacitance, controlling inrush currents poses problems. The simplest approach involves placing an inrush-limiting resistor in series with the capacitor bank, but a resistor wastes power and adds a voltage drop. ...

Reducing low-frequency (1/f) noise generated by an IC voltage reference can prove difficult. In theory, adding a lowpass filter to a reference's output reduces noise. In practice, a lowpass RC filter for suppression of noise frequencies below ...

For most applications, current measurements are made by sensing the voltage drop across a resistor. There are two locations in a circuit that resistors are commonly placed for current measurements. The first location is between the power supply and ...

One of our products uses a standard 1/10-W surface-mount resistor with a high-side current monitor to detect small load changes at the product’s output. Since this circuit is part of the device’s output, it’s vulnerable to field ...

TI Application Report Introduction For several years Quad-flat no-leads (QFN) package with thermal pad have been standard starting point for high current designs. Technology and trends pushed buck converters to get even smaller and more efficient. ...

For redundancy purposes, a number of power supplies, using ORing diodes, can work into the same load. During maintenance, when you can remove any power supply, the minimum possible power perturbation at the load is desirable. To compensate for the ...

Switching Battery Inc., has unveiled an innovative electronic method for the connection of batteries called para-series. The patent-pending para-series method is based on dynamically switching a group of batteries between series and parallel ...
