Power entry module equipped with double-stage filter
Modern electronic equipment is designed to deliver high performance in a compact size. Often this causes problems affecting the equipment itself or other nearby devices due to the inherent electro-magnetic interferences being generated in and between the different systems. To meet these EMC challenges, high performance power entry modules must also keep pace, and such is the case with the new DD14 series from SCHURTER.
GaN power portfolio expanded with small and fast GaN drivers
Expanding on its Gallium Nitride (GaN) power portfolio, Texas Instruments has announced two new high speed GaN Field-Effect Transistor (FET) drivers to create more efficient, higher performing designs in speed-critical applications such as Light Detection And Ranging (LIDAR) and 5G Radio Frequency (RF) envelope tracking. The LMG1020 and LMG1210 can deliver switching frequencies of 50MHz while improving efficiency and enabling five times smaller s...
DC/DC controller eliminates external surge protection devices
Analog Devices has announced the Power by Linear LTC7810, a high voltage non-isolated dual output synchronous step-down DC/DC controller that drives all N-channel MOSFET power stages. Its 4.5-140V (150V abs max) input voltage range is designed to operate from a high input voltage or from an input that has high voltage surges, eliminating the need for external surge suppression devices.
Tech enables higher power densities in smaller form factors
Global supplier of electronic components, KEMET, has announced new patented KONNEKT technology enabling high power density by combining multiple components into a single surface mountable package. This technology is designed for use by power electronics engineers where high-power density in a small form factor is critical.
Tackling the extreme battery design challenge
With more devices being designed for use in challenging environments, one of the numerous benefits of technology is that it allows businesses to optimise operations in extreme conditions. However, this presents a challenge for original equipment manufacturers (OEMs) tasked with designing these products. In this article Michele Windsor, Global Marketing Manager at Accutronics, looks at how design engineers can tackle the extreme challenge.
DC/DC converters cope with high switching voltages
Availability and full design support capabilities for two series of DC/DC converters from RECOM Power has been announced by Richardson RFPD. High slew-rate GaN transistors require an isolated 6V supply with high isolation voltage and low isolation capacitance.
Next-gen devices improve switching efficiency
Nexperia has announced its NextPower 100V family of power MOSFETs which delivers low reverse recovery charge (Qrr) and includes parts that are qualified to 175°C in the LFPAK56 (PowerSO8) package.
Buck battery charger cuts power supply size and charge time in half
Texas Instruments has introduced several new power management chips that enable designers to boost efficiency and shrink power-supply and charger solution sizes for personal electronics and handheld industrial equipment.

Learn how to use Fusion Digital Power Designer software to control the TPSM846C23 EVM through the PMBus interface.
High power semiconductor crowbar protector for AC power lines
AC power line disturbances are the cause of many equipment failures. The damage can be as elusive as occasional data loss or as dramatic as the destruction of a power supply, LED lightings, industrial system and consumer equipment such as ovens or refrigerators and television sets.
