Description Introduction about IC parts BP5220A, BP5221A

The electronic components BP5220A, BP5221A, electronic component BP5222A, are DC / DC  converters that use a pulse width modulation (PWM) system. They contain control circuits,  switching devices, rectifiers, and coils, and operate by only connecting an I / O  smoothing capacitor.

With a high efficiency of power conversion, the modules are available in stand-alone
9-pin SIP packages with no heat sink required. They can be applied to various purposes by  fine-adjusting the output voltage and switching on and off. With a wide range of input  voltage, the modules are best suited for obtaining a stable local power supply from a main power supply with a large voltage variation.

Description Introduction about IC parts 74LVX161284A

The electronic components LVX161284A contains eight bidirectional data buffers and eleven  control/status buffers to implement a full IEEE 1284 compliant interface. The device  supports the IEEE 1284 standard, with the exception of output slew rate,and is intended to  be used in an Extended Capabilities Port mode (ECP). The pinout allows for easy  semiconductor connection from the Peripheral (A-side) to the Host (cable side).

Outputs on the cable side can be configured to be either open drain or high drive (± 14  mA) and are connected to aseparate power supply pin (VCCcable) to allow these outputs
to be driven by a higher supply voltage than the A-side. The pull-up and pull-down series  termination resistance of these outputs on the cable side is optimized to
drive an external cable. In addition, all inputs (except HLH) and outputs on the cable  side contain internal pull-up resistors connected to the VCCcable supply to provide  proper termination and pull-ups for open drain mode.

Description about Ic components VND5004A-E and VND5004ASP30-E Features

The electronic components VND5004ATR-E and electronic component VND5004ASP30-E are devices made using STMicroelectronics VIPower
technology. They are intended for driving resistive or inductive loads with one side connected to ground.

Active VCC pin voltage clamp and load dump protection circuit protect the devices against transients on the Vcc pin (see ic components ISO7637 transient compatibility table). These devices integrate an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is high impedance.

Output current limitation protects the devices in overload condition. In case of long duration overload, the devicesa limit the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.

description information of electronic components lm358dr

These devices consist of two independent,high-gain, frequency-compensated operational
amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the electronic components LM2904), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage.

Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational amplifier circuits that now can be implemented more easily in single-supply-voltage systems. For example, these devices can be operated directly from the standard 5-V supply used in digital systems and easily can provide the required interface ic components without additional ±5-V supplies.

The Components of the ic components SP212-A

The ic components SP212-A Components follows:

The electronic component  SP212-A utilizes one of JBL’s finest cone transducers, the 2206H. The 12" 2206H is part of JBL’s family of Vented Gap Cooled woofers and carries an AES power rating of 600 watts with minimal power compression. The cone has been treated for weather
resistance.

The 25 mm (1 in) exit electronic components 2426H compression driver with its pure titanium diaphragm is the acoustic motor in the new computer designed OASR (Optimized Aperture Symmetrical
Radiator), the result; broad symmetrical pattern control with clear HF.

The application field of Ic components lm358

Introduction application field of Ic components lm358,do you know?
Application areas include transducer amplifiers, dc gain blocks and all the
conventional op amp circuits which now can be more easily implemented in single power
supply systems. For example, the LM158 series can be directly operated off of the
standard +5V power supply voltage which is used in digital systems and will easily
provide the required interface electronics without requiring the additional ±15V
power supplies.
The LM358 are available in a chip sized package (8-Bump micro SMD) using National’s
micro SMD package technology.

Introduction to the function about Diode


Diode is One of the electronic components,here the function about Diode :
1.A diode allows current to flow in one direction onl
2.It consists of 2 pieces of silicon, each 'doped' with a different chemical (e.g. phosphorus and boron) to make one more positively charged than the other. The more positively charged piece attracts negatively charged electrons more than the other and this permits a one-way flow.

3 Diodes need greater than 0.7 volts to work.
4.To convert AC to DC, you must use a full wave rectifier that consists of 4 linked diodes.:
