SC1704-331

Fixed Inductors

Fixed inductors are coils that store energy in the form of electromagnetic fields. They are considered “fixed” because they do not require the energy to be applied in any specific form to generate the electric field. A good example of a fixed inductor is the SC1704-331. This device is a 3-terminal synchronous rectified synchronous buck converter with a small package size and very efficient output power. The SC1704-331 is designed for applications such as general consumer electronics, digital audio, portable communication devices, and computer peripheral devices.

The SC1704-331 uses a synchronous rectified buck converter to achieve high power efficiency with low component costs. It has a maximum input voltage of 28 V and provides a constant output voltage of 3.3V, allowing for both high power efficiency and cost savings. It is also capable of handling 4A output current without additional cooling or thermal protection.

The working principle of the SC1704-331 is based on the transformer effect. When a current passes through one part of the circuit, an electromagnetic field is generated which induces a voltage in the other part of the circuit. This voltage is then used to create the output voltage. The SC1704-331 uses an input voltage equal to the output voltage, allowing the transformer effect to produce a voltage conversion.

The SC1704-331 also incorporates a few other features to increase its efficiency. These include a built-in soft start, overvoltage protection, over temperature protection, and reverse current protection. The soft start helps to ensure that the output voltage is not exceeded when the input voltage is suddenly changed, while the overvoltage protection prevents the device from generating a voltage higher than the desired setting. The over temperature protection prevents the device from overheating, and the reverse current protection prevents it from becoming damaged in case of a reverse current.

The SC1704-331 is a fixed inductor device that is used in various types of applications. Its robust design and reliable operation make it an excellent choice for applications where high power efficiency and cost savings are desired. The device can also be used to provide voltage conversion for output voltages that are higher or lower than the input voltage.
