Within the world of electronics developments in Power can be crucial to design engineers. At New Electronics we are aware of the importance of staying abreast of the recent advances in and the impact it can have on your role, that’s why we have collated all the latest news in one place.

Compact 75V DC input EMC filter is rated at 50A

The RDEN-048050 48V DC nominal EMC filter rated at 50A has been introduced by TDK. Enclosed in a compact metal case, the filter uses stud terminals for ease of connection. Excluding the terminals, the filter measures 90 x 60 x 30mm.

AC/DC modules provide high power density

Luso Electronics has introduced Qualstar’s N2Power branded XR125RE and XR125 AC/DC power supplies in the UK and Ireland. The modules are said to provide the highest power density at 125W power output.

Regulator protects load by tripping power source

The LTM4636-1 from Linear Technology is a 40A to 240A scalable step down µModule switching regulator. The part incorporates protection circuitry that trips a circuit breaker in the event of overvoltage or over temperature fault conditions to protect itself, the PCB and loads – including high current low voltage processors, FPGAs, GPUs and ASICs.

No-opto flyback regulator delivers up to 15W

The LT8315 from Linear Technology is a high voltage monolithic flyback regulator that is said to simplify the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation.

I²C battery monitor measures state of charge parameters

The LTC2944 multicell battery monitor from Linear Technology makes direct measurements of 3.6V to 60V battery stacks. Level shifting circuitry on the supply and measurement pins is not required to interface with multicell voltages, so total current consumption is minimised and measurement accuracy is preserved.

Medical power supplies offer Class I or Class II inputs

The DTM300 series from TDK is a family of level VI medical 300W external power supplies. Certified to the latest IEC 60601-1 and 60601-1-2 medical standards, the products have 4000V AC isolation from input to output and are offered with either a Class I or Class II input.

How small diameter electrolytic capacitors in power supplies can impact reliability and cost

Recently a member of TDK-Lambda’s technical marketing team experienced first-hand just how much influence small diameter electrolytic capacitors can have on long-term power supply reliability. Unfortunately he picked February to have his central heating system upgraded and Britain’s unpredictable weather system delivered snow! The 7-year old boiler system in the loft had been turned off for two days while the radiators were replaced. When the installation was complete, the boiler was switched on, but failed to start.

Rohde & Schwarz introduces a probe with very large offset range

The RT-ZPR20 is an extremely low-noise power rail probe with a bandwidth of 2 GHz. Developed by Rohde & Schwarz its 1:1 attenuation ensures very good sensitivity and a large offset range of ± 60 V permits analysis of the smallest disturbance signals during power integrity measurements, even on DC power supplies with a high voltage level.

Desktop power supplies meet energy standards

Four series of external/desktop power supplies from XP Power meet the latest level VI and Code of Conduct (CoC) Tier 2 green standards. The single output power supplies are suitable for customers requiring a low power, external, 18, 24, 30 or 36W power source for their new designs that need to meet current legislation.

MOSFETs for quasi resonant flyback topologies

The 700V CoolMOS P7 family has been developed by Infineon Technologies to serve the trend in quasi resonant flyback topologies. The MOSFETs are said to offer performance improvements compared to currently used superjunction technologies which could help improve soft switching topologies like smart phone and tablet chargers.

Multiphase 60V synchronous boost controller

The LTC3897 from Linear Technology is a multiphase synchronous boost DC/DC controller with input surge stopper and ideal diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements.

XP Power offers encapsulated 80W AC/DC modules

The ECE80 series of 80W single output AC/DC encapsulated power supply modules from XP is said to have low no load input power. The modules are suitable for customers requiring a solution in a compact format for either PCB, chassis, or DIN rail mounting.
