Introduction

The BD95841MUV-E2 is a high performance, step-down, synchronous, DC-DC converting switch-mode regulator. It integrates two high and low-side power switches with low ON resistance and offers a wide input voltage range capability of 4.25 V to 35 V. It is suitable for all types of systems that require high current and high switching frequency, such as high end Graphics Card, cellular phones, ultra-portable PCs, LCD TV and other digital series with low standby power consumption.

Application Field

The BD95841MUV-E2 can be used in all applications which required high current and high switching frequency, such as high end graphics card, high-burst current wireless communication devices, portable audio products, digital display and automotive. The wide input voltage range capability, adjustable output voltage and high maximum output current make it suitable for multi-use loads and provide a reliable supply voltage.

Working Principle

The BD95841MUV-E2 works on the principle of converting DC input voltage to a regulated output voltage in a switch mode configuration. The BD95841MUV-E2 includes two power switches, high-side and low-side and operates in PWM (Pulse-width Modulation) mode. Incoming DC voltage is chopped into voltage pulses for which the On/Off ratio is controlled using a dedicated feedback control loop. The overall efficiency of the DC-DC conversion is related to the On/Off ratio, along with the frequency and inductor size. The chip also provides adjustable output current protection based on the output current sense signal and synchronous rectification technology.

Conclusion

In conclusion, the BD95841MUV-E2 device is a high performance, step-down, synchronous, DC-DC switch-mode regulator that integrates two high and low-side power switches. The adjustable output voltage, wide input voltage range capability and high maximum output current make it suitable for multiple uses. This device is suitable for applications which required high current and high switching frequency and has a wide application field in Graphics Card, cellular phones, ultra-portable PCs, LCD TV and other digital series with low standby power consumption field.
