International Rectifier has introduced the IRS2336xD protected 600V three-phase gate driver ICs with integrated bootstrap functionality for appliance motor control, servo drives, micro-inverter drives, and a wide range of general purpose applications.

Avago Technologies has announced a thin ultra-compact innovative input device solution that combines a navigation pad module with a motion sense and interface integrated circuit (IC) to provide a mouse-like pointing solution for use in a variety of mobile devices. Typical applications include mobile phones, ultra-miniature PCs, digital still cameras, computer peripheral and other handheld and gaming applications. With a low profile height of 1.7 ...

Linear Technology has announced the LTC3219, an inductorless, low noise, high efficiency LED driver for cell phone displays and lighting. The IC provides nine individually configurable current sources for Main, Sub and RGB displays. Display currents are set via a precision internal current reference. The universal current sources can be digitally controlled with independent dimming, brightness, blinking, and gradation control, programmable via a ...

Schaefer, Inc. has introduced the C300 and B300 Series’ of 150W DC/DC Converters, AC/DC Power Supplies, and Battery Chargers. The C300 DC/DC product line boasts 7 DC input ranges of 10-16V, 18-36V, 36-75V, 45-90V, 80-160V, 160-320V, and 320-380V with 10 single output voltages ranging from 5VDC to 220VDC. The C300 AC/DC Series offers the same range of output voltages from a choice of 110VAC, 230VAC, or 115-230VAC inputs. The BP200 Series of...

The new A6281 from Allegro MicroSystems Europe is a three-channel constant-current LED driver IC with an on-chip oscillator for simple programmable brightness control. The new device is ideally suited to driving clusters of red/green/blue (RGB) LEDs in applications where the cluster forms one pixel in a large display or a lighting fixture. It precisely controls LED brightness via 10-bit pulse-width modulation (PWM) on each channel, complemented...

Linear Technology has introduced the LTC4264, a Power over Ethernet (PoE) interface controller for high-power Powered Device applications. The LTC4264 allows users to develop power-hungry applications beyond the IEEE 802.3af-mandated 12.95W limit, while still maintaining backward compatibility. The LTC4264 can deliver up to 35W for 2-pair systems and as much as 70W for 4-pair systems. To control turn-on surge current in the system, the LTC4264 i...

Yuasa Battery has launched a new long life standby 12V valve regulated leadacid (VRLA) battery that is designed especially for use in telecommunications power applications. The new Endurance ENL10012FT battery features a 15 year design life and has been designed from the ground up to fit into standard telecom equipment racks. Both terminals are at the front of the cell making it easier to connect batteries when situated in power cabinets.

Fairchild Semiconductor is helping power supply designers achieve higher levels of efficiency in less space with seven new STEALTH II fast-recovery diodes. These STEALTH II rectifiers feature fast reverse recovery and soft recovery characteristics that enable reduced MOSFET switching losses and EMI in continuous-current-mode (CCM) power factor correction (PFC) designs. Alternate solutions provide snappy reverse recovery, but this is at the expens...

Power Sources Unlimited has added to its high performance DC/DC converter offering with the Tracopower THN-15 and THN-15WI Series’ of 15 Watt modules. These converters feature either a 2:1 input or a 4:1 input with tightly regulated, isolated, adjustable, single outputs of 3.3VDC, 5VDC, 12VDC, or 15VDC.

Catalyst Semiconductor has announced the CAT6221 300mA, dual-output LDO. The CAT6221 integrates two 300mA regulators in a tiny, 6-lead, 0.8mm height TSOT-23 package, providing a smaller, cost-effective option for cell phones, battery-powered devices and other portable consumer products requiring two LDOs.
