Optimizing the energy efficiency of converters and controllers
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 […]
12:1-input quarter-brick dc/dc converters key on railway apps
Two 40-W and 60-W dc/dc converter series come in quarter-brick packages with an ultra-wide input voltage range of 14 to 160 Vdc making them a good candidate for railway rolling stock applications and high voltage battery systems. The 12:1 input voltage range of RECOM’s RP40Q-RUW and RP60Q-RUW series covers all input voltages from nominal 24 […]
Low-profile DOSA converters hit 99% efficiency
New power modules offer one of the highest power densities in a DOSA footprint on the market with a profile of only 3.75 mm. They provide either 1, 2, 3, or even 6 A in the same-sized package for scalability. The 6-A module has at least 50% higher power density than its peers on the […]
Bi-directional synchronous buck-boost controllers
Renesas Electronics announces an innovative new family of bidirectional four-switch synchronous buck-boost controllers. The ISL81601 and ISL81401 are the industry’s only true bidirectional controllers that sense peak current at both ends and provide a cycle-by-cycle current limit in both directions while in buck or boost mode. The controllers generate point-of-load (POL) and voltage rail conversions […]
Nonsynchronous boost controller that drives two MOSFET stages
Analog Devices announces the Power by Linear LTC7840, a 2-phase nonsynchronous boost controller that drives two stages of external N-channel power MOSFETs. It is configurable as single or dual output boost regulator or for higher voltages, the output of the first channel can feed the input of second channel allowing an output voltage which exceeds several […]
Buck-boost controller targets 12-V/12-V redundant battery systems in autonomous vehicles
The Power by Linear LT8708/-1 is a 98% efficient bidirectional buck-boost switching regulator controller that operates between two batteries that have the same voltage, as are used for redundancy in self-driving cars. The LT8708/-1 operates from an input voltage that can be above, below or equal to the output voltage, making it well suited for […]
Scopes handle SPMI protocol decode for debugging mobile-device power controllers
Tektronix, Inc.today introduced protocol decode, triggering and analysis support for the MIPI Alliance’s System Power Management Interface (SPMI) for its 5 and 6 Series MSO mixed signal oscilloscopes. The new software option takes advantage of the leading-edge capabilities of these oscilloscopes including the productivity of touch-based setup, one of the industry’s largest 15.6-in HD display […]
PMBus-compliant digital controllers deliver eight phases and >240A
Renesas Electronics Corporation announced two new PMBus compliant, fully digital DC/DC controllers that provide single output point-of-load (POL) conversions for FPGAs, DSPs, ASICs, network processors and general purpose system rails. The ISL68300 with integrated MOSFET drivers and ISL68301 with PWM output simplify designing power supplies for data center, wired and wireless communications, and factory automation […]
