The BD9111NV-E2 is a highly efficient voltage regulator that operates as a DC DC switching regulator. It is one of the Silent Switcher series products of Rohm Semiconductor, released in 2021. The compact, 4-channel devices are excellent choices for LED lighting, battery-powered devices, and other applications where silence and minimal power consumption are important factors. The BD9111NV-E2 is also equipped with onboard over-current, over-voltage, and over-temperature protection.

The BD9111NV-E2 achieves its high efficiency through the incorporation of a synchronous rectifier, also known as a synchronous rectification scheme. This helps reduce the power loss associated with the conventional diode rectification scheme, which results in a higher efficiency. Compared to the traditional diode rectification scheme, the synchronous rectification scheme also keeps the device cooler, allowing it to operate at lower temperatures.

In addition, the BD9111NV-E2 boasts a high power conversion ratio of up to 94%, which allows for efficient power usage. The device also supports Pulse Width Modulation (PWM) or pulse-frequency modulation (PFM) operation. The PFM allows the device to handle higher currents and react faster to input voltage variations.

The BD9111NV-E2 is capable of providing up to 1.5 amp of continuous current with a peak current rating of 3.0 amps. The output voltage is adjustable via external resistors, which allows for fine-tuning of the output voltage. The output frequency can be adjusted via the onboard trim resistor to maximize efficiency. The device also features soft-start functionality and short-circuit protection.

The BD9111NV-E2 is suitable for a wide range of applications, including LED lighting, battery-powered devices, home appliances, and consumer electronics. Its high efficiency, small size, and low noise make it an attractive choice when considering a voltage regulator for such applications. Its PWM/PFM operation, adjustable output voltage, and onboard over-current/over-temperature protection further makes it ideal for these types of applications.
