Technology trends for increased PoL power densities
The power density of point of load (buck) converters (PoLs) has been increasing for several decades. It is driven by a combination of component improvements and advanced power conversion technologies that produce the increases in power conversion efficiencies needed to support higher power densities. Where are we now? And what’s next? Power density is an […]
Sager Electronics to handle Vox Power VCCS300 conduction-cooled ac/dc supplies
The Vox Power VCCS300 series of conduction-cooled ac/dc power supplies are 300-W units producing continuous output power in just a 2x4x1.61-in package. The all-in-one solution can be cooled using conduction, convection, or forced air cooling techniques.

APEC 2022, to be held in Houston, Texas, from March 20-24, 2022, continues the long-standing tradition of addressing issues of immediate and long-term interest to the practicing power electronics engineer. APEC is now accepting submissions for the first of its 2022 speaker deadlines, the Technical Program Papers. Interested authors wishing to present a Technical Program […]
What’s a voltage regulator module?
A voltage regulator module (VRM) is a specialized point-of-load (PoL) power converter, sometimes called a processor power module (PPM). Like other PoLs, VRMs are buck converters. They are specifically designed to convert a 5V or 12V bus to a specific voltage needed to power a central processing unit (CPU) or graphics processing unit (GPU) in […]
Low-voltage automotive LED backlight drivers incorporate boost converter
Maxim Integrated Products, Inc. introduces the four-channel, low-voltage MAX25512 automotive LED backlight driver with an integrated boost converter. It is the only integrated solution that retains the full, constant brightness of in-car displays even during extreme cold crank conditions down to 3V input voltage. The single-chip LED driver eliminates an external MOSFET and current sense resistor and […]
350-500-W medical/industrial supplies deliver up to 1 kW peak
TDK Corporation announces the introduction of the TDK-Lambda brand CUS350MP-1000 AC-DC medical and industrial certified power supplies. Capable of providing 500W with external airflow (1,000W peak), the series is rated at 350W when convection cooled and can deliver peaks of 800W for up to 5s. This makes the CUS350MP-1000 suitable for low audible noise applications […]
What are Point-of-Load converters?
Point-of-load converters (PoLs) are used in distributed power architectures (DPAs) to step down a relatively high power distribution bus voltage to the lower voltages needed by system components such as microprocessors, ASICs, and other digital ICs. DPAs are used in systems of all sizes to improve power distribution efficiency. Larger systems tend to use higher […]
