XP Power targets high volume, cost-sensitive markets
XP Power has announced the VCT60 series of 60W, single output AC/DC power supplies, the first of its new V-Brand range of low cost power supplies. Fitting into a standard 1U space, measuring 50.8 x 101 x 24.1 mm (2 x 4 x 0.95in) the units are ideal for designers requiring an economical power supply that can fit into an industry standard 2 x 4in footprint.
Synchronous Buck Converter with Only 12uA Quiescent Current from Linear Technology
Linear Technology has announced the LTC3642, a 45V input capable synchronous buck converter than can deliver up to 50mA of continuous output current from a 3mm x 3mm (or MSOP8-E) package. It operates from an input voltage range of 4.5V to 45V with transient protection up to 60V, making it ideal for automotive and industrial 4mA to 20mA control loop applications.
Fairchild Announces 20V MicroFET MOSFET
Fairchild Semiconductor brings designers of portable applications a 20V 2mm x 2mm x 0.55mm thin MicroFET MOSFET that provides what it says is the lowest RDS(ON) in the industry. The FDMA6023PZT is a dual P-Channel MOSFET in a compact, low profile package that answers the portable design challenge requirements for thinner and smaller applications that are equipped with technology that conserves battery life.
Sunpower's SPS-100 Single Output Power Supplies
Sunpower has re-designed its 100W Single Output Power Supplies to make more suitable for low consumption and environmental protection purposes. The newly designed circuit is built-in new PWM control IC which brings the max. output wattage up to 110W (for 48V output) under natural cooling environment.
High Input Voltage DC/DC Controller from Linear Tech
Linear Technology has announced a new high reliability (MP) grade version of the LT3724, a 60V (65V(MAX)) low quiescent current (100uA) switching regulator DC/DC controller used in step-down, step-up, inverting and SEPIC topologies. The LT3724MP operates, and is 100% tested, over a junction temperature range of -55°C to 125°C, compared to the I grade version's -40°C to 125°C operating temperature range.
UNIPOWER’s new Rectifiers and Front-Ends combine power densities of 23.4W/in³ with 92% efficiency levels
UNIPOWER has announced its latest generation of high-density, hot swappable 48VDC modular rectifiers and front-ends. Called BLUEstreak, the series combines high power density with high efficiency levels. The Front–end version will be factory set at 48VDC while the Rectifier version will be set at 54.4VDC.
