Renesas is aiming at Intel’s Core Ultra 200V series of processors with a pair of power ICs. RAA225019 is a six-phase buck converter, designed to work with IMVP9.2 Lunar Lake processors. Integrated within is the switching controller, power mosfets and current-sensing. “Six phases can be distributed across three outputs – two SVID rails and one auxiliary rail,” said Renesas. “SVID1 ...

Vishay has stretched an SO-6 package to accommodate 1kV operation from opto-based mosfet and IGBT gate drivers. The body is ~7mm from end to end and creepage is 8mm. Clearance is 7mm for the ‘option 9’ package which has conventionally bent legs, or 8mm for the ‘option 8’ package which has widely-splayed legs (see image). Peak working voltage is 1.14kV ...

Infineon is looking towards 1,500V dc links with a 2kV 80A silicon carbide Schottky diode. IDYH80G200C5 is the 80A 2,000V part, which comes packaged in four-lead TO-247PLUS-4-HCC, with 14mm creepage and 5.4mm clearance. Only two of the leads are used – the two adjacent to the creepage slot. The cathode is connected to the separated pin as well as the ...

ProTek Devices has introduced a pair of 15kW transient voltage suppressors for 28V aircraft circuits. “The devices meet compliance for MIL-STD-704 and MIL-STD-19500, in addition to being RTCA DO-160G compliant,” according to the company. They are called: PAL704-P15K36 is 50 x 19 x 12mm 30g with flat terminals PAL704-P15K36T 63 x 23 x 17mm x 48g with turret terminals Both ...

Toshiba has filled out its TCKE9 electronic fuse and voltage-clamping IC family with two products: TCKE903NL clamps its output between 3.64 and 4.1V and latches off after tripping – cycling the enable pad re-starts it TCKE905ANA clamps its output between 5.4 and 6V and auto-tries after tripping Although not regulators – they are designed to work fully-on – they voltage ...

Vicor has released three automotive-grade power modules for 48V electric vehicles: a bidirectional 2.5kW 800V to-from 48V converter, a 2kW 48V to 12V regulator and a 2.5kW 48V to 48V regulator. The unregulated fixed-ratio 2.5kW isolated bi-directional 800V to-from 48V dc-dc converter is a member of the BCM6135 family, with a power density of 158kW/litre according to the company. “The ...

Vox Power Ltd has announce the EIRE300 series of 300W open-frame ac-dc power supplies for medical and IT equipment use, that measure 4 x 2 x 1inch. 300W is with forced air and only 200W (115Vac) is available continuously if only convection cooling is available – with ambient temperature caveats. Up to 375W can be delivered for 1s. Different models ...

Flex Power Modules has launched a 750W intermediate bus converters at the OCP Global Summit in San Jose. Fitting in to the Open Compute Project’s (OCP’s) OAM V2.0 footprint (41.47 x 17.67 x 6.9mm) BMR321, as it will be known, is unregulated and has a fixed 8:1 conversion ratio to take an input between 40 and 60V and produce a ...

Infineon has created a fast-disconnecting 125V load switch for fault protection in cordless power tools, e-bikes, battery-powered robots and battery vacuum cleaners. Packaged in a 5 x 6mm DSO-8, 1EDL8011 includes a charge-pump to drive the gate of the external high-side n-channel mosfet that does the switching. There are actually two charge pumps: a high-capacity on using the external capacitor ...

TDK-Lambda has introduced 200W non-isolated dc-dc converters in the 1 x 1inch PCB-mount industry package. In each case, the output can be adjusted across 9.6 – 28V and can be up to 10A and up to 200W. Called i1C, they actually measure 26.42 x 26.42 x 10.2mm. There are two input ranges: i1C2W010A120V-00x-R parts work from 9 – 36V (max ...
