Here’s how to evaluate energy efficiency associated with components that make up widely used power conversion circuitry. FRANK DE STASI, MATHEW JACOB, TEXAS INSTRUMENTS INC. IN SOME WAYS, selecting a module, converter or controller for power conversion resembles deciding whether to take a flight, board a train, or drive from point A to B. Once […]

Compact synchronous silent switcher provides 5 V, 10 A
Analog Devices announces the Power by Linear LTC3310S, a 5V, 10A low EMI monolithic synchronous buck converter. The device’s fixed frequency peak current mode architecture is ideal for high step-down ratio applications that demand fast transient response. The LTC3310S uses the Silent Switcher 2 architecture with integrated hot loop bypass capacitors to deliver a highly efficient, small footprint […]
Eval boards check power modules for trimming, sequencing, soft starts and sensing functions
RECOM’s eval boards for the RPM‐1.0, RPM‐2.0, RPM‐3.0, and RPM‐6.0 buck regulator series generate a constant output voltage with an output current up to 6A from an external DC source. The multitude of functions offered by the RPM power modules such as trimming, sequencing, soft‐start, enable, and sensing can be evaluated. More importantly, the behavior […]
Implementing full digital power control for LDOs
Today’s power supplies require flexible power solutions and more digital control than a decade ago, especially in the server cloud computing market. The days of de-soldering resistors and capacitors to tweak a voltage control loop are long gone. Historically, digital power control started with a single-phase, point-of-load (POL) regulator with PMBus interface. Today, it has […]
BGA package option comes to 48-V ZVS buck regulator series
Vicor Corporation announced the PI354x-00-BGIZ, the latest addition to the 48V Cool-Power ZVS Buck Regulator portfolio, offering a new BGA package option to the existing PI354x-00-LGIZ LGA series. PI354x Cool-Power ZVS Buck Regulator’s high-performance ZVS topology enables 48V direct to PoL without sacrificing performance. With step-down regulation from a higher voltage source, engineers can deploy […]
Step-down ultrathin regulator module handles ASIC, FPGA loads
Analog Devices announces the Power by Linear LTM4686, a dual 10A or single 20A ultrathin step-down µModule regulator with a PMBus interface housed in a 16mm x 11.9mm x 1.82mm LGA package. The 1.82mm package height allows the LTM4686 to be placed on a PC board very close to its load such as an FPGA or […]
Are power systems up to the task of running self-driving cars?
Automotive electronics depends on power supplies that can handle abuse like load dumps. New ICs are optimized for these extreme environments and can meet stringent vehicle safety standards. Tony Armstrong, Analog Devices Inc. THE auto industry expects a transition to autonomous vehicles via both an evolutionary path, where existing cars get there little by little […]
