Fixed inductors are electronic passive components consisting of conductive wire wrapped around a ferromagnetic core, primarily used to provide semi-permanent inductance in an electrical circuit. One of the most common examples of a fixed inductor is the 84223C. The 84223C is an integrated circuit used in highly efficient and low voltage power converters. It is a linear integrated circuit that combines the features of a voltage-mode Pulse Width Modulated (PWM) controller IC with an oscillator, driver, power MOSFET, bootstrap capacitor, thermistor, and an inductor, all included in a single package.

The 84223C is suitable for a wide range of applications, such as switching power supplies, battery chargers, DC to DC converters, and uninterruptible power supplies. It is also ideal for applications requiring a high efficiency, such as laptops, PDAs, and mobile phones. Its small size makes it ideal for use in compact designs.

The 84223C carries out the voltage-mode PWM control. In this type of control, the amplitude of the reference voltage and the duty cycle of the pulse width modulated switching waveform that it produces remain unchanged, regardless of the load power. The PWM generator has a programmable reference voltage, an adjustable frequency of switching pulses, and a built-in low power sleep mode.

The 84223C oscillator has an on-chip, high gain comparator that is designed for low voltage operation. Its adjustable frequency output can be used to control the operation of either low or medium power switch controllers. It has an on-chip power MOSFET, which is suitable for applications needing a fast rise-time and an accurate control cycle time.

The 84223C has an on-chip bootstrap capacitor which ensures a high efficiency operation of the MOSFET, even when the voltage on the bootstrapping capacitor is low. The power MOSFET also has an on-chip thermistor to reduce the device operating temperature and to increase its reliability.

The 84223C integrated circuit also includes an on-chip inductor with a complex winding structure. This inductor provides a low current start-up, a high output voltage, and a very low voltage offset. It is designed to increase the efficiency of the power control system.

In summary, the 84223C is an integrated circuit that combines several features of a voltage-mode PWM controller, an oscillator, a driver, a power MOSFET, a bootstrap capacitor, a thermistor, and an inductor in a single package. It is suitable for a wide range of applications, such as switching power supplies, battery chargers, DC to DC converters, and uninterruptible power supplies. The 84223C can increase the efficiency of power control systems and is ideal for applications needing a high efficiency, such as laptops, PDAs, and mobile phones.
