450W medical power supply boasts compact design
HiTek Power is now offering a medical power supply (compliant with IEC60601-1 – 3rd Edition) that boasts a compact footprint, high level of effectivity of 90% and some additional special features. With convection cooling, this device produces 300W and with a 23.5 CFM fan, it can even be loaded to 450W.
Switch incorporates 85mΩ Pch MOSFET
A power switch optimised for USB 2.0 and 3.0 applications, as well as power line distribution and Hot plug applications, has been launched by Torex. The XC8107 device incorporates 85mΩ Pch MOSFET power switch for low ON resistance.
50W DC/DC converter targets Power-over-Ethernet applications
Suitable for Power-over-Ethernet (PoE), as well as 24 or 48V telecomms systems applications, Ericsson has introduced a 50W DC/DC converter module. The PKU5510E features an ultra-wide input range of 18-75V, an output current of 15A at 3.3V output and a built-in functional isolation of 2250V DC that meets the requirements specified by the IEEE802.3 Ethernet networking standard.
DC/DC converters for industrial and automotive use
Suitable for a variety of industrial and automotive applications, the LT8471 is a dual DC/DC converter from Linear Technology. It uses two internal 2A, 50V switches and an additional 500mA switch to facilitate multi-topology functionality: step-down, step-up and inverting conversions.
LDO regulator increases design flexibility
The AZ2085 adjustable LDO regulator, from Diodes Inc, has a minimum load current of just 1mA, a maximum of 3A and an adjust pin current of only 6µA which makes the device, the company claims, able to handle a far wider range of applications than alternative DC linear voltage regulators.
DC/AC inverters meet 48VDC power supply demands
The PJN series of DC/AC inverters, launched by Powersolve, can provide between 1000 and 4500VA from a DC input between 40 to 60VDC, making them suitable for telecoms systems with a 48VDC power supply.
Power capacitors feature higher energy density
Extending the company's range of EPCOS MKK power capacitors, TDK announce the MKK DCi-R series B25640 with resin impregnation. Based on the proven MKK DC series with gas impregnation and MKK DC-I with oil impregnation, the series includes capacitors that are rated at up to more than 10 000μF and designed for voltages of up to 4000 V DC.
Press-pack 6.5V IGBT includes fully rated anti-parallel diode
Featuring asymmetrical blocking with a fully rated anti-parallel diode included within the package, the T0258HF65G press-pack IGBT has been launched by IXYS UK. The 6.5kV device has a DC collector current rating of 258A with a repetitive peak current rating of over 500A, further extending the power range of IGBT power switches.
Regulators support POL supplies of 8A, 12A & 15A
Adding to the existing PowerBlox family of DC-DC converter products, Exar have introduced the XR76108, XR76112 and XR76115 synchronous step down regulators. Supporting POL supplies of 8A, 12A and 15A, respectively, the devices deliver core voltage rails for ASICs, FPGAs, DSPs and Network Processors in communications, networking and industrial markets.
Drivers extend life of multi-cell Li-ion batteries
Intersil has claimed that the HIP2103 and HIP2104 are the industry’s first small form factor half-/full-bridge drivers that significantly extend power usage and overall product life of 5-50V multi-cell lithium ion (Li) battery devices. These bridge drivers have a configurable topology to facilitate half-bridge, full-bridge and three phase motor-driven applications.
