Discrete Design Description This DC-DC converter design regulates the three-output power supply rails for use in a remote patient vital sign monitor subsystem. The circuit provides proper line and ...

Noise: Noise manifests as high-frequency voltage spikes on the programmable power supply’s output voltage. No matter how good it is, a DC programmable power supply will cause noise on the output ...

Read the introduction to this series in Part 1, and the conclusion in Part 3, which covers stability. This is Part 2 of a three-part series which discusses how to properly test a DC/DC power supply to ...

It is a common belief that multi-layer ceramic capacitors (MLCCs) or DC power supply circuits cause audible noise, but that’s not true. The noise is generated by the PCB, not by the components. The ...

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...

Renesas is aiming at powering automotive cameras with an ISO-26262 compliant multi-rail regulator IC – qualified to AEC-Q100 Grade 1. RAA271082 has a primary high voltage synchronous buck regulator, ...

Its original trimpot was replaced with a multi-turn pot for ease of control. To make everything work, a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard.
