Compact dual LDO regulator offers high accuracy
A dual 300mA LDO regulator that offers high 1% output accuracy and a low quiescent current of 50μA is currently being offered from Diodes Incorporated. The AP7344 features a small package to suit battery-powered consumer products such as cameras, smart phones and tablets.
Power module combines an IEGT & fast recovery diode
Suitable for use in rail traction, industrial motor control, renewable energy systems and electricity transmission and distribution applications, the MG1200GXH1US61 power module has been released by Toshiba Electronics Europe. The 4500V, 1200A device integrates an N-channel IEGT and a fast recovery diode into a standard package with a footprint of just 140x190mm.
Electrical isolation in medical device setups
The increased complexity of medical device setups is causing concern in the medical industry. As more and more healthcare professionals use a variety of electrical equipment as part of their diagnosis and measurement regime, there is a knock-on effect on the stability of the mains power supply. Here, Steve Hughes, Managing Director at REO UK, explains the importance of electrical isolation and good product design.
DC/DC converter offers high efficiency & thermal performance
Delivering up to 50A with a single fully regulated 12V output, a series of 600W quarter-brick isolated DC/DC converters has been unveiled by Artesyn Embedded Technologies. The ADQ600 series has an input voltage range of 40 to 60V and is primarily designed for use with standard 48V supplies in computing and server applications, as well as regulated 48V supplies in telecomms equipment.
