A DC-DC switching regulator, such as the BD9329EFJ-E2, is a type of integrated circuit that is capable of providing a constant output voltage from an input voltage range. This makes the switching regulator ideal for applications such as monitoring and control systems, where outputs such as current must be maintained within a certain range.

The BD9329EFJ-E2 is a 3-channel constant LED current sink DC-DC switching regulator, designed specifically for LED driving applications. It is equipped with a high-accuracy current control, and a protection circuit that prevents damage to LEDs by limiting the current to a safe value.

The BD9329EFJ-E2 provides an adjustable constant output current when its inputs are driven by non-DC voltage. This guarantees that the LED current remains constant even when external conditions change. A common application of the BD9329EFJ-E2 is providing a constant LED current for LED backlighting applications in digital displays, such as LED TVs, computers and tablets.

The BD9329EFJ-E2 includes a power MOSFET, a 3-channel current regulator, a protection circuit, and a charge pump for generating a negative voltage. The power MOSFET can switch current up to 2A, which is suitable for driving a wide range of LED currents. The output current is adjustable using an external resistor.

In addition, the BD9329EFJ-E2 has a built-in thermal protection circuit to minimize the risk of thermal damage in cases of overcurrent or over temperature. The protection circuit can detect changes in the ambient temperature surrounding the device and will shut off the output if the temperature rises above a certain level.

The BD9329EFJ-E2 is designed to provide a highly efficient constant-current power supply, ideal for applications where the output current needs to be accurately controlled, such as lighting and signage. The current control accuracy of the device is ±2%, and its operating temperature range is -40°C to +85°C.
