The HIP6521CBZ is a type of linear + switching power management integrated circuit (PMIC). It is specifically designed for the purpose of power regulation, offering five output channels configured in either a 3+2 or 2+3 configuration. It’s built-in ladder and switching structure allows for quick and energy-efficient conversion of input voltage to output voltage levels when needed. The device is also capable of offering a wide range of output levels, allowing it to be used in a variety of applications.

This type of PMIC is useful in applications that require a certain input voltage level to be maintained despite the available line voltage fluctuating. By doing this, it prevents any disruption of a sensitive load that is powered by the device. The HIP6521CBZ can also be used for stepping an input voltage up or down to provide a demand-specific supply voltage for the load.

The HIP6521CBZ operates as an adjustable DC-DC converter as well as providing a set of related power management functions, such as voltage sequencing, sequencing delay, and over-voltage protection. To ensure reliability and optimum performance, the HIP6521CBZ incorporates overcurrent and over-temperature protection features, along with monitoring and thermal shutdown capabilities. The device also includes protection circuitry which avoids excessive inrush current when the device is powered up, thereby preventing current surges.

To provide more accurate voltage regulation and fast transient response, the HIP6521CBZ can also be supplemented with external power components. The integrated feedback circuit in the device accounts for output voltage level stability and provides accurate output voltage control to the load. In order to lower the power consumption during stand-by operation, an adjustable voltage UVLO threshold allows the device to enter stand-by mode when the input voltage is below the adjusted threshold.

Due to its wide input voltage range, the HIP6521CBZ is suitable for applications in various fields. For example, it can be used in battery-powered portable audio devices, PC modems, routers, and other communication devices; and it can also provide power supply for TV controllers, industrial motors and other motor-drive applications. In its 3+2 (or 2+3) configuration, the HIP6521CBZ ensures power to five independent loads, where each load can be powered by two outputs.

The HIP6521CBZ from Intersil is a low cost, high performance PMIC specifically designed for efficient power management and voltage regulation, with a wide range of features to suit all kinds of applications. The device’s integrated ladder and switching structure can be easily adapted to provide a custom regulated output voltage, while its wide input voltage range, integrated protection features, and standby mode make it an ideal solution for a variety of design requirements.
