LDO Regulator from Torex
Torex has unveiled the XC6501 Series of high-speed LDO voltage regulators. Featuring internal phase compensation, these devices ensure a stable output within a 1.2V to 5V range, without requiring a CL capacitor. The XC6501 is therefore an ideal choice for providing voltage regulation in space-constrained designs such as mobile phones, portable gaming devices and cameras.
75W DC/DC converter with 4 to 1 wide inputs and optional terminal block
MEGA Electronics Inc. has released our PD75W series of 4 to 1 wide input 75 watt DC/DC converters in an industry standard half brick footprint. The six sided continuous shielded converter has efficiencies to 90% with 15A of output current.
Sixteenth Brick Delivers 3.3V @ 25A and Exceptional Elevated-Temperature Performance
Power-One, Inc. introduces the SSQE48T25033 DC-DC Converter. This DOSA-compliant sixteenth brick provides 3.3 VDC @ 25 amps with 100% of full-rated power available at 55°C, and 22 amps @ 70°C, using only 200LFM airflow. Tight regulation (+/-3% combined line, load, and temperature), and efficiencies up to 93% make this an ideal DPA or IBA power source for communications, data server/storage, and workstation applications.
National Semiconductor Introduces Industry’s First Differential Wideband Amplifier with Programmable Output Limiting Clamp
National Semiconductor Corp. today introduced the industry’s first wideband 900 MHz fully differential amplifier to include a programmable output limiting clamp for protecting analog-to-digital converters (ADC) and other downstream circuitry from over-voltage events. The amplifier’s integrated clamp provides improved distortion, higher bandwidth and clamping accuracy compared with existing amplifiers that must use external discrete clamping c...
New Siliconix 25-V TrenchFET(R) Gen III Power MOSFET
Vishay Intertechnology, Inc. today expanded its family of Gen III TrenchFET® power MOSFETs with the release of a new 25-V n-channel device offering the industry’s lowest on-resistance and on-resistance times gate charge for a device with this voltage rating in the PowerPAK® SO-8 package type.
Ultralow Supply Current Monitors Ideal for Portable Electronics
Linear Technology has introduced the LTC2934 and LTC2935, ultralow power supply monitors that only draw 500nA of quiescent current. Battery life is of the utmost importance in portable applications, where it is essential to reduce the amount of supply current the device draws during normal and standby operation. It is important to minimize quiescent current in supporting power components like voltage monitors in an effort to prolong battery life....
