Space-saving packages for regulator transistors

Space-saving packages for regulator transistors
Designed for 48V circuits in networking, telecomms and PoE equipment, Diodes Incorporated announce new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors. Device inputs are actually tolerant up to a maximum of 100V, meaning all regulator transistors offer plenty of headroom in the event of transient over-voltage conditions.

2W DC/DC converter offers 50% smaller footprint

2W DC/DC converter offers 50% smaller footprint
Believed to be the industry’s smallest 2W converter, the MTU2 series of ultra miniature surface mounted 2W DC/DC converters have been announced by Murata. Measuring just 8.2x8.4x8.5mm with a 0.69cm2 footprint, it is 50% smaller than the current 1.67cm2 industry standard. Load regulation is typically 5% better than other products available on the market, reducing the need for any additional regulation components.
