45V input 200mA LDO offers active output discharge
Linear Technology announces the LT3063, a high voltage, low noise, low dropout voltage linear regulator with active output discharge. The IC delivers up to 200mA of continuous output current with a 300mV dropout voltage at full load. The LT3063 includes an internal NMOS pull-down that discharges the output voltage if either the SHDN pin is driven low or the input voltage is turned off.
AC/DC Power Supplies Ensure Continuous Operation
CUI have announced the release of a new AC/DC power supply family targeting applications that demand 100% uptime. Available in 75 W, 100 W and 155 W configurations, the PSF series is designed with built-in battery charging and back-up functionality. Under normal operating conditions, the units are able to charge the stand-by battery and also supply direct power to the load.
Device enables high efficiency in server & datacom systems
Combining two power MOSFETs and a DC/DC driver IC with integrated current and temperature sensing, the DrBlade 2 power stage device has been introduced by Infineon. The low-profile package of the device, which uses galvanic and lamination processes to reduce footprint and height, aids engineers of server and datacom applications in handling high power density requirements and in shortening design-in cycles.
Regulators deliver 95% efficiency in half the solution size
Achieving up to 95% efficiency, the 1A TPS63050 and 4A TPS630250 buck-boost regulators have been launched by Texas Instruments. Providing 95% effciency in half the solution size when compared to competing products, the company claims that the single-inductor devices are the industry’s smallest and highest performance buck-boost regulators currently on the market. The devices have been designed to extend battery life in Li-Ion battery-powere...
Low RDS(ON) MOSFETs for industrial applications
A family of Large Can DirectFET MOSFETs has been introduced by International Rectifier. The devices are suitable for industrial applications requiring ultra-low on-state resistance (RDS(ON)) including high power DC motors, DC/AC inverters, and high current switching applications such as active ORing hot swap and eFuse.
400W power supply is ruggedised for MIL applications
Designed for MIL and industrial applications, the 7602 Compact PCI power supply has been introduced by Gresham Power Electronics. The ruggedised 6U AC/DC power supply is able to be factory modified to a wide range of output voltage configurations on all four outputs or it could be factory set to be a single output version of 12-48V DC rated at 600W.
1200V IGBTs boost energy efficiency
Energy efficiency is on all agendas and to help meet this requirement STMicroelectronics’ has introduced 1200V IGBTs that leverage second-generation trench-gate field-stop high-speed technology to boost energy efficiency and ruggedness in applications such as solar inverters, welders, uninterruptible power supplies, and Power-Factor Correction (PFC) converters.
USB switching charger IC integrates fuel gauge
Designed for the Chinese USB powered smartphone market, as well as tablets and emerging wearable devices, Dialog Semiconductor announce a highly efficient switching charger IC. The DA9150 features an integrated fuel gauge to measure the state of charge of the battery with 99% accuracy, allowing system firmware to maximise battery run time for consumers who increasingly depend on portable devices.
PWM controller for desktop and server applications
Designed for high-end desktop and server applications, a six-phase pulse-width modulation (PWM) controller compliant with Intel’s VR12/12.5 specification has been announced by Intersil. The ISL6388 features multiple time programmable NVM that allows for the creation of custom configurations during the design process, eliminating the need for a soldering iron to make adjustments.
Lithium battery operates at higher temperatures
Ismosys has followed up its recent appointment to represent the components division of Seiko Instruments (SII) in the UK and Ireland by releasing a new coin-cell lithium rechargeable battery that offers a much higher operating temperature than conventional rechargeable batteries.
