The BD83850GWL-E2 is a special purpose voltage regulator. It is a high-current step-down silicon carbide (SiC) synchronous regulator that realizes power conversion from 125V to 0V. This device is perfect for applications where high speed, high accuracy, synchronization, and real-time control are necessary.

The BD83850GWL-E2 controller is designed for applications such as telecom and server power supplies, industrial motor drives, infotainment systems, and automotive systems. This device supports a wide voltage range of 40V to 125V, with a maximum output current of 10A and a switching frequency up to 2MHz. The highly efficient synchronous power conversion provides excellent power loss and thermal management.

The BD83850GWL-E2 includes a dedicated synchronizer (SYNC) pin and a two-stage control loop that is capable of monitoring and adjusting the voltage at the output directly. This makes the device an ideal candidate for applications that require synchronization and real-time control. Additionally, the device also features over voltage protection (OVP), under voltage protection (UVP) and over temperature protection (OTP) for enhanced system reliability.

The device also features a hardware ramp compensation that minimizes inductor current overshoot and reduces switching losses thereby improving system efficiency. The device also has advanced protection features such as over current protection (OCP), short circuit protection (SCP), fault latency monitoring (FLM) and external supply current monitor (ESCM). Additionally, the device also has an adjustable under voltage lockout (UVLO) which prevents the device from operating at low input voltages and a synchronous rectifier fault detection (SRFD) to protect the system from operational faults.

The BD83850GWL-E2 can be easily integrated into existing power supply systems and its high switching frequency reduces external component count. Additionally, the device is pin-compatible with the existing industry leading BD83850GW-E2 family. This provides high design flexibility and makes it easy to upgrade existing systems.

In conclusion, the BD83850GWL-E2 is an ideal special purpose voltage regulator for applications where high speed, high accuracy, synchronization and real-time control are required. It offers high efficiency, low power loss and enhanced system reliability with a variety of protection features. Additionally, it also provides high design flexibility and easy integration into existing systems.
