For over two decades, the 80 Plus rating system has been a measurement of a power supply's energy efficiency. A power supply ...

A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices.

and a “power good” circuit to tell the motherboard that the PSU is ready and to activate the supply on an external input. Alan Liefting [PD], via Wikimedia Commons. These supplies are slightly ...

Input-to-output isolation is 5000VDC, input-to-ground 3100VDC, and output-to-ground is 750VDC. The D1SE models are convection-cooled and rated for operation in -25C to +70C ambient temperatures, with ...

This requires a relatively high-voltage input power supply and results in low power efficiency. A low dropout (LDO) linear voltage regulator is a type of linear voltage regulator circuit that works ...

Analog power supply 2.0V ~5.0V; ; Ultra-low power dissipation structure, as low as 80/160nA; ; Shutdown current is lower than 5nA; ; ... The nSPLL_SIL130G_1V2 cell is a fully-programmable PLL IP cell ...

This single-chip, highly integrated active-clamp current-mode PWM controller solution is designed for isolated power supply and Power ... with a wide 8V to 80V input range. It is optimized for ...
