The HIP6004BCVZ is a highly integrated level shift regulator intended for automotive applications. It functions as a single-stage linear regulator, providing adjustable output voltage from 5V to 42V. In comparison to conventional linear regulators, the HIP6004BCVZ can reduce quiescent current, reduce board area, and have lower thermal stress. This makes it ideal for automotive power conversion applications such as HVAC, ECU, Car audio, Lights and other accessories.

HIP6004BCVZ Application Field

The HIP6004BCVZ is based on the principle of level shifting, a technique used to take energy and convert it to a different voltage in order to supply power to specific components. The device is intended for automotive applications, specifically for applications that require a regulated output voltage from 5V to 42V and where the input voltage is either 12V or 24V. This makes it useful for automotive HVAC, ECU, car audio, lights and other accessories such as USB interfaces, power supply systems and power amplifiers.

As a single-stage linear regulator, the HIP6004BCVZ provides stable output voltage and is suitable for low-noise operating environment. It is a load-independent, voltage-tracking device and its high efficiency up to 95% achieves low power dissipation. This makes it a perfect choice for automotive applications, providing all the benefits of a linear regulator such as high immunity to noise and improved light load performance.

HIP6004BCVZ Working Principle

The HIP6004BCVZ functions as a level shift regulator, with its input connected to either a 12V or 24V power source and its output connected to a load requiring an adjustable voltage up to 42V. This is achieved by introducing a differential voltage between source and load in order to maintain the output voltage. This differential voltage is created by the device’s internal charge pump.

The charge pump is a two-stage circuit consisting of two switch (SW1, SW2) networks connected in series. During each cycle, SW1 pumps charges from the source to the output, while SW2 pumps charges from the load to the output. The difference in charge between the source and load is maintained by the charge pumping effect. This differential voltage is then used to regulate the output voltage, maintaining it at a preset value.

The usefulness of the HIP6004BCVZ lies in its ability to increase efficiency and reduce board area. As a single-stage linear regulator, it can provide up to 95% efficiency and can reduce quiescent current while still delivering excellent load and line regulation. As such, the HIP6004BCVZ is a perfect choice for automotive power conversion applications.
