60W open frame AC-DC medical-grade power supply
Expanding SL Power's line of high-density open frame AC-DC medical-grade power supplies, the new MB60S is a single output 60 watt AC-DC PSU. Supplied in an ultra-compact 2" x 3" x 1.0" package, this convection cooled power supply is certified for use in both patient vicinity and patient contact applications, including blood pressure monitors and ultrasound equipment.
MOSFET family meets differing cost/performance points
The new AP4034 family of 30V N-channel enhancement-mode power MOSFETs have been unveiled by Advanced Power Electronics. Available in several popular package alternatives to meet differing cost/performance points, the AP4034 family provides fast switching performance and feature a low typical gate charge of 15nC for good switching performance.
Ultra-low forward voltage Schottky barrier diodes
Extending its portfolio of surface mount Schottky barrier diodes, Toshiba has introduced the CxS15S30 device. Based on the latest Toshiba semiconductor process, the new SBD features improved forward voltage and reverse current performance. The CxS15S30 is ideal for space-limited applications requiring high current handling and low forward voltage.
High-accurate charge/discharge control in new ICs
A new member of ROHM's IC series, providing high-accurate charge/discharge control, monitoring and protection functions for Li-ion secondary battery packs, has been anounced today. The ML5218 is a Li-ion battery monitoring IC for packs of 5 up-to 16 cells detecting over-charge or over-discharge and over-current of each cell. This makes the device adaptable to systems using safer lithium iron phosphate batteries of multiple cells connected in seri...
New PFC controller cuts power consumption in half
Texas Instruments has announced the release of the UCC28180 8-pin power factor correction controller. Featuring the industry's widest range programmable frequency operating in continuous conduction mode, the UCC28180 delivers power factor correction greater than 0.95 and also cuts power consumption in half, compared to existing solutions.
Regulator increases power system design efficiency
The new ZL2102 signals an expansion by Intersil of their industry-leading family of power management ICs. The ZL2102, a 6 Amp digital synchronous step-down DC/DC power regulator, is a fully integrated regulator able to support adjustable output voltages of 0.54V to 5.5V operating from input voltages from 4.5V up to 14V.
Compact metal power inductors feature profile of just 1.0mm
The new VLS-HBX series of compact metal power inductors has been announced by TDK. Featuring a high current capability and profile of just 1.0mm, the two new types have footprints of 2.0 mm x 1.6 mm and 2.5 mm x 2.0 mm respectively. Due to the use of a magnetic metal core material with a high saturation flux density, the power inductors offer rated currents of up to 6.0 A DC, depending on type.
MEAN WELL extends middle wattage models with RSP-100 series
MEAN WELL have unveiled the RSP-100 series, a 100W AC/DC low profile single output enclosed type switching power supply with PFC function, which extends their middle wattage offering. The RSP-100 series lowers its height, reduces the size by 33%, and increase the efficiency by 8% when compared to the preceding models of the SP-100 series.
Automotive brushed DC motor driver ICs
Expanding its line-up of small sized brushed DC motor drivers for automotive applications, Toshiba introduce the TB9101FNG and TB9102FNG motor driver ICs. Supplied in a 5.6 mm x 7.8 mm SSOP24 package, the TB9101FNG and TB9102FNG feature on-resistances of 0.6Ω (Typ.) and 0.5Ω (Typ.), respectively, and can drive up to two and six motors, respectively.
Battery charging controller for solar applications
Linear Technology have announced a new synchronous buck-boost battery charging controller for lead acid and Lithium batteries, the LT8490. Featuring automatic maximum power point tracking, temperature compensation, and many selectable constant-current constant-voltage charging profiles, the LT8490 is ideal for charging a variety of Lithium or lead acid chemistry types, including sealed lead acid, gel cells and flooded cells.
