ACAL has available Microchip's MCP1827 and MCP1827S low output voltage, high output current Low Dropout Regulators (LDOs). The new LDOs are available in small, thermally efficient 3- and 5-pin packages, and support output currents up to1.5A.

Fairchild Semiconductor has introduced the FPF100x family of IntelliMAX load switches featuring industry-leading packaging (WL-CSP or MLP), integration (slew-rate control, ESD protection and load-discharge capability) and best-in-class low-voltage operation (1.2V).

Powersolve has announced the TXL Series of enclosed power supplies. Available as single, dual and triple output units, the 60 model series will interest designers and specifiers across a broad range of AC to DC applications.

HiTek Power has introduced the XR150 high-precision X-ray power supply. This modular unit is rated at 150W and meets the exacting demands of today’s high-performance industrial X-ray systems because of its low output ripple, high-accuracy filament monitoring and control, as well as an extremely stable beam-current loop.

SL Power Electronics Corporation, the company established following the merger of Condor DC Power and Ault, announces a new range of external power supplies designed to meet the requirements set forth by the Environmental Protection Agency’s ENERGY STAR Program.

Microchip announces an online Intelligent Power-Supply Design Centre to provide the technical resources needed to design analogue power supplies, augment existing analogue power supply designs with inexpensive microcontrollers, or design Switch-Mode Power Supplies (SMPS) with full digital control of the power-conversion feedback loop. The site offers direct access to all of Microchip’s power-supply application notes, reference designs and other...

Texas Instruments has introduced a family of high voltage-input low-dropout linear regulators designed to withstand the requirements for harsh operating environments. The new devices offer a wide input voltage range of up to 45 V, providing transient protection for applications such as automotive body controllers, instrument clusters, automotive audio and telematics.

Vicor has added eight mid-power Maxi DC/DC converters to its 375Vdc input family: a 200W model at 3.3Vout, a 300W model at 5Vout, and 400W models at 12, 15, 24, 28, 36, and 48Vout. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — are appropriate for off-line systems with auto-ranging or PFC front ends in industrial or process control, distributed power, medical, ATE, communicati...

Power Integrations has introduced a reference design kit for an energy-efficient charger/adapter based on its LinkSwitch-LP family of integrated circuits with EcoSmart technology. The new reference design kit (RDK-83) reduces no-load power consumption by 79 percent compared to existing linear solutions, and features a constant-voltage (CV) charger circuit capable of withstanding 10 kV common-mode / 2 kV differential-mode surges.

Semtech Corp has announced the SC4612, a 28V synchronous buck power converter with a wide input range and a programmable 1.2 MHz frequency for compact power supply designs. It is a voltage-mode synchronous, PWM controller that operates in a 4.5V to 28V input voltage range and drives external N-channel MOSFETs.
