Part 1 Three-level (3L) buck off-chip components and their losses Off-chip losses include those across the equivalent series resistance (ESR) in the input, output and flying capacitors, as well as the inductor. Choosing ceramic capacitors with very ...

Introduction Modern portable electronic devices require a high-capacity Lithium-ion battery to power popular features such as high-definition cameras, edge-to-edge high-resolution touchscreens and high-speed data connections. As a result, charging ...

Using impulse radios as an example, we'll examine the advantages of ultra-wideband (UWB) technology compared to other short-range wireless communication technologies. Ultra-wideband (UWB) is a short-range wireless communication technology - ...

Minimizing noise is a common challenge for engineers designing a power supply for noise-sensitive systems for test and measurement and radio applications, such as clocks, data converters or amplifiers. Although the term “noise” can mean ...

What’s the difference between power and energy density, and why is the former so vital to power-supply design? Let’s find out. To design robust power supplies, designers need to understand some basics and pitfalls. Is power density the ...

1. Why NextPCB created NextDFM? According to statistics, 60% of the product cost depends on the initial design of itself. 75% of the manufacturing cost depends on the design specification. 70%-80% of production defects are caused by design. DFM has ...

Increasing power conversion efficiency and power density has always been the primary goal for the power supply industry. Over the past decade, there has been phenomenal progress thanks to the development of power devices, topologies, and control ...

You can use an ADT7461 single-channel temperature monitor; an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer; and three standard 2N3906 p-n-p transistors to measure the temperature of three separate remote thermal zones (Figure 1). ...

The two-chip circuit in Figure 1 provides fan control and overtemperature warning and shutdown signals to protect systems from excessive heat. The circuit monitors the temperature of the pc board and the die temperature of a CPU, an FPGA, or ...

Resistive dividers attenuate high voltages down to a level that low voltage circuits can accommodate without getting overdriven or damaged. In power path control circuits, resistive dividers help set up power supply undervoltage and overvoltage ...
