Mobile Charger Common-Mode Noise Measurement

Mobile Charger Common-Mode Noise Measurement

Common-mode noise voltage pulses from AC-DC chargers can affect the signal reception of capacitive panels during charging, which may lead to inaccurate touch readings or false touch signals. This has prompted cell phone manufacturers and the International Electrotechnical Commission (IEC) to jointly develop the IEC 62684 Standard to harmonize charger interfaces. Charger manufacturers are looking […]

Chroma Test Systems Fill The Bill For ATX12VO Power Supply Testing

Computer chip specifications are evolving at a rapid pace. This drives industry associations and other organizations in the power conversion field to keep raising their efficiency requirements and certification standards. As a result, the ATX12V Power Supply Design Guide launched by Intel in 2000 is no longer suitable to serve as a standard for today’s […]

How to Test a DC-DC Converter for Quality and Reliability

This post describes how to test a DC-DC converter. DC-DC converters are devices used to convert one DC voltage to another. DC-DC converters are used in a wide variety of products from portable devices such as cell phones, notebooks and laptop computers to electric vehicles and avionics. The range of input voltages and output voltages […]

Electronic Load for Low Voltage, High Current Applications

As server computers and networking systems become more powerful, point of load DC/DC voltages for CPUs are continuing trend lower (below 1V) while demanding higher currents. To satisfy the needs of test engineers, we have released a new DC electronic load for low voltage, high current applications. The 63206A-60-1000 DC Electronic Load provides up to […]
