Regulator generates DDR2, 3, 3L & 4 SDRAM voltages
Capable of generating the bus termination voltages needed by DDR 2, 3, 3L and 4 SDRAM memory systems, a low-dropout linear regulator has been released by Diodes Incorporated. The AP2303 regulator, which is suitable for next-gen set-top boxes, mother boards and graphics cards, continuously sources and sinks current up to 1.75A.
Ballast transformers suit aerospace lighting systems
Suitable for aerospace, industrial and commercial lighting systems, the Lighting Ballast Transformer series has been introduced by Innovative Power. To start lighting systems and regulate current for efficient operation, the transformers control the voltage. Featuring a scalable open-frame design, the transformers are suitable for applications which require high electrical performance, reliability, long-life and a low lifecycle cost.
Micro PLC platform targets factory efficiency
Integration is carved in stone outside Maxim Integrated’s new headquarters in San Jose. The company has been pursuing a strategy of packaging more of its products to work together to provide customers with a more cost effective and efficient path to market. The strategy’s latest produce is the Micro PLC (programmable logic controller) platform which consists of five reference designs which can operate as stand-alone subsystems and be ...
Medical AC/DC power adapters operate at 90-264V & 47-63Hz
A series of low cost medical grade AC/DC desktop power adapters has been released by TRUMPower. The TMP92 series includes both a class I and class II unit. While the class I is designed with an IEC 320/C6 AC inlet with a ground pin, the class II unit is designed with an IEC 320/C8 AC inlet without a ground pin.
S-Band GaN power products shorten time-to-market
Designed for commercial air traffic control, weather radar and military radar applications, a portfolio of surface mount S-Band GaN power products has been released by M/A-COM Technology Solutions. The portfolio includes the MAMG-002735-030L0 30Wpk GaN amplifier, the MAMG-002735-085L0L 85Wpk GaN amplifier and the MAPG-002729-350L00 350Wpk aluminium-based pallet.
Share current across multiple DC/DC digital PWM controllers
A dual-phase, DC/DC digital PWM controller, designated the ZL8801, has been introduced by Intersil. Capable of sharing current across multiple devices, the controller's range can be extended up to 300A for high-end FPGAs and ASICs employed in densely populated power supplies in servers, storage equipment and basestations.
BLDC motor gate drivers consume 5µA in sleep mode
Integrating a power module and a LIN transceiver, Microchip has introduced two 3-phase BLDC motor gate drivers. Suitable for battery-powered or energy-efficient motor applications in the industrial and automotive sectors, the MCP8025 and MCP8026 drivers offer a typical low sleep current of 5µA and can act as Master or Slave in low-power standby mode.
Rectifiers meet next-gen battery charger efficiency targets
Enabling next-gen battery chargers to achieve efficiency and temperature targets, the Trench Super Barrier Rectifier (SBR) series has been launched by Diodes Incorporated. The 15A SBRT15U50SP5 and 20A SBRT20U50SLP rectifiers are the first in the series to be released by the company. While the former is suitable for 10W smartphone chargers, the latter suits 12.5W tablet chargers.
Op amps utilise just 3fA bias current at 25°C
Designed for high speed and high dynamic range transimpedance amplifier (TIA) and buffer applications, the LTC6268 and LTC6269 FET-input single and dual op amps have been released by Linear Technology. Resolving input currents from several femtoamps to amps, the devices utilise 3fA bias current at 25°C and 4pA max over the -40°C to 125°C temperature range.
