HIP6021CB-T is the high-end current control driver integrated circuit. It integrates all of the high-end current control, such as the linear regualtor, the buck regulator and the power switches to provide the enhanced system performance.

It also supports various communications protocols such as I2C, UART, SPI, PCC and LIN. This IC can be applied to various application fields, including industrial, home appliance, consumer electronics, and automotive.

From its application field, the HIP6021CB-T IC is grouped as a voltage regulator and is classified as the linear-switching IC. This type of IC is mainly applied in applications that require high-end current control but not very accurate voltage-level. This is mainly because it offers more power at greater efficiency than linear voltage regulator.

To elaborates on its working principle, the primary operation of the linear-switching regulator is that input voltage is converted to the required, low-ripple output voltage. This operation is achieved through switching techniques which demands the high-performance IC like the HIP6021CB-T. This IC works efficiently and reliably in the application.

To be more specific the IC contains two separate channels with two independent voltage regulators on each channel. The combined output of the two regulators creates a much lower output voltage level than the combined input voltage, achieving the required output voltage. This process is also called a cascaded regulation.

The major components of the linear-switching regulator are the input circuit, the voltage reference circuit and the error amplifier. The input circuit consists of the inductor, the rectifier, the output filter, and the PWM circuit. The rectifier is used to change the alternating current (AC) input voltage into a direct current (DC) voltage.

The error amplifier is used to compare the reference voltage with output voltage and convert the difference into a control voltage. This is used to alter the PWM frequency and AC load conditions, thus controlling the output voltage. The output filter is then used to filter out the switch frequency signals, creating a more stable output voltage.

The voltage reference circuit is used to keep the output voltage stable. This is done by controlling the operational amplifiers and setting the reference voltage. Finally, the PWM circuit is used to regulate the input voltage through the MOSFET switches. This is done by altering the duty cycle of the PWM signal, thus controlling the output voltage.

To sum up, the HIP6021CB-T IC is an impressive current control integrated circuit which is mainly employed in the industrial, home appliance, consumer electronics, and automotive systems. As a linear-switching IC, it is mainly used to power the system and provide the high-end current control, while the PWM circuit, error amplifier, and voltage reference circuit help to regulate the output voltage level.
