The BU90009GWZ-E2 is a DC-DC switching regulator that belongs to the Voltage Regulators under Power Management ICs (PIMCs). It is suitable for automotive use and is specifically designed to meet the requirements of vehicles’ on-board systems, including communication systems, navigation systems, and entertainment systems.

The BU90009GWZ-E2 is a step-down DC-DC converter, offering high efficiency and excellent thermal performance. With its low on-resistors and operating temperature range of -40℃ to +125℃, the device can easily support automotive high-current loads and a wide range of working temperatures. It can continuously provide a maximum output current of 9A and delivers a regulated voltage at its output terminal of 1.5V to 7 V. With its built-in transistor, the device can easily provide a high step-down ratio between the input and output voltage. Furthermore, the current consumption can be accurately regulated, providing constant voltage or current at the output terminal even with sudden loading changes.

In terms of application, the BU90009GWZ-E2 is widely used in various automotive systems such as power steering, air conditioning, communication systems, navigation systems, and entertainment systems. Its wide range of operation and high step-down conversion capability make it an ideal solution for providing power for these vehicle systems.
