IR3832W SupIRBuckTM is a highly efficient synchronous buck regulator from IR company, which can be applied to DDR memory applications. This product supports wide input voltage range (1.5V-16V), wide output voltage range (0.6V-0.9*Vin), and maximum continuous output current of 4A.
BF988 is a dual gate MOS field-effect tetrode with integrated gate protection diodes, high cross modulation performance, low noise figure, high gain, high AGC-range, low feedback capacitance, and low input capacitance. It is suitable for input and mixer stages, especially for VHF and UHF tuners.
The LTC1255 is a dual 24V high-side MOSFET driver that allows using low cost N-channel FETs for high-side industrial and automotive switching applications. An internal charge pump boosts the gate drive voltage above the positive rail, fully enhancing an N-channel MOS switch with no external components. Low power operation, with 12µA standby current, allows use in virtually all systems with maximum efficiency. Included on-chip is independent overcurrent sensing to provide automatic shutdown in case of short circuits. A time delay can be added to the current sense to prevent false triggering on high in-rush current loads. The LTC1255 operates from 9V to 24V supplies and is well suited for industrial and automotive applications. The LTC1255 is available in both an 8-pin DIP and an 8-pin SOIC.
The VLWTG9600 is a clear, non-diffused LED designed for applications where high luminous flux is required. It utilizes highly developed InGaN technology and has supreme heat dissipation, allowing it to be used at high ambient temperatures. All packing units are binned for luminous flux, forward voltage, and color to achieve the most homogenous light appearance in application.
This application note describes how to drive RGB LEDs, how to calculate a power dissipation, how to design an over temperature protection, how to use a software PWM modulation and why over voltage protection should be implemented for this kind of application.
The ADC081S051 is a low-power, single channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. It is fully specified over a sample rate range of 200 ksps to 500 ksps and is based on a successive-approximation register architecture with an internal track-and-hold circuit. The output serial data is straight binary and compatible with several standards. The ADC081S051 operates with a single supply ranging from +2.7V to +5.25V. Power consumption ranges from 1.6 mW to 8.5 mW depending on the supply voltage. The power-down feature reduces power consumption to as low as 2.6 µW. The ADC081S051 is available in 6-lead LLP and SOT-23 packages and is suitable for operation over the industrial temperature range of -40°C to +85°C.

LM2597/LM2597HV SIMPLE SWITCHER® Power Converter 150 kHz 0.5A Step-Down Voltage Regulator is a switching power supply IC with adjustable output voltage and can be equipped with different external components.
The QT240 charge-transfer (“QT’”) QTouch IC is a self-contained digital sensor IC capable of detecting near-proximity or touch on 4 electrodes. It allows electrodes to project independent sense fields through any dielectric like glass, plastic, stone, ceramic, and wood. It can also turn metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability coupled with its continuous self-calibration feature can lead to entirely new product concepts, adding high value to product designs.
