Photonic Products has announced a new high visibility, short wavelength laser diode from Sanyo which offers a very high optical output power of 40mW CW with a low threshold current of 60mA in a 9mm package.

Texas Instruments Incorporated expands its high-voltage point-of-load product line by introducing today the industry’s first 100-V synchronous buck regulator with integrated MOSFETs. The 600-mA LM5017 is the first in a new family of step-down switching regulators that reduce PCB area and system cost while improving high-voltage reliability. Used in conjunction with the award-winning WEBENCH online design tool, the LM5017 simplifies high-vol...

Texas Instruments has announced an integrated +/-1C maximum remote junction temperature sensor and local temperature sensor, designed to monitor thermal diodes found in CPUs, microprocessors, graphics processing units and FPGAs. Unlike other devices, the TMP411 features programmable series resistance cancellation and diode non-ideality correction which simplify and remove the time-consuming process of individual processor resistance calibration c...

Texas Instruments has introduced a device based on a high-frequency synchronous-boost topology with constant current sink to drive single, high-brightness white light emitting diodes (LEDs). The tiny 2 mm x 1.5 mm x 0.625mm device uses an inductive fixed-frequency pulse-width modulation (PWM) control scheme using small external components, minimizing input ripple current for applications, such as a white LED flash for camera phones, smart phones ...

STMicroelectronics has introduced a device that provides an extra channel of ESD (Electro-Static Discharge) protection within the same dimensions as competing alternatives — 25% more channels to deliver a space-efficient solution for designers of feature-rich, tightly packed portable gadgets such as netbooks and smartphones.

STMicroelectronics today announced an innovation for solar panels aimed at allowing more of the energy from each cell to reach the power grid. The innovation replaces the simple bypass diode with an intelligent device that enhances efficiency and offers the same package outline. The new device can deliver a fast Return-On-Investment, in terms of releasing additional energy for solar panel applications.

Texas Instruments has introduced the industry’s first integrated, eight-channel, transmit/receive (T/R) switch for ultrasound systems. The TX810 addresses designers’ need to build smaller portable ultrasound systems, while speeding time to market.

Renesas Technology Europe today announced the CRD5CM reverse conducting thyristor for use in voltage regulators for two-wheeled vehicles and engines for general-purpose batteries. The CRD5CM integrates a thyristor and a rectifier diode in a single element. Sample shipments will begin in February 2010.

With a few discrete components and some creative thinking, spare microcontroller peripherals can be used to provide a low-current, regulated voltage boost, as Keith Curtis, Technical Staff Engineer, Microchip Technology Inc. explains.

Renesas today announced the availability of its new control IC (part number μPD168891) for automotive light emitting diode (LED) headlights. The main features of the μPD168891 IC are (1) an integrated current-control function for constant-current drive of LEDs as well as a pre-driver function for driving external metal-oxide-semiconductor field-effect transistors (MOSFETs); (2) integrated protection functions essential for automotive a...
