S6BP401AJ2SN1B000 is a linear, switched-mode and polyphase voltage regulator manufactured by ROHM Semiconductor. It is a multi-function integrated power control device designed to provide high efficiency, high accuracy and low power loss in various voltage regulation applications such as personal computers, servers, cell phones, and other portable electronics.

This product operates in the voltage range from 3.0 V to 24V and provides single output voltage options up to 6V. It has a high switching frequency of 2 MHz which helps to reduce input and output filter size. The overcurrent protection circuit and the overvoltage protection circuit helps to protect the device from overloading or from other malfunctions. It has a wide range of operation temperatures from -40℃ to +95℃ and is available in a LQFP-64 package.

Application field: S6BP401AJ2SN1B000 is suitable for various kinds of applications, such as PC main board, server main board, notebook main board, tablet main board, communication equipment, LED and DC LED driver, cell phone charger, small electronic products and medical equipment and portable electronic device.

Working Principle: The S6BP401AJ2SN1B000 utilizes a PFM (Pulse Frequency Modulation) voltage regulator control principle to regulate the output voltage. When the current load is low, the regulator works in PFM (light-load) mode and keeps switching at a fixed frequency. This helps to minimize the power consumption and the noise generation. When the load current increases, the regulator senses the load current and automatically switches to Pulse-width modulation (PWM) mode, thus providing stable voltage regulation. It also includes an error amplifier that helps to maintain an excellent voltage regulation accuracy and a feedback loop control to maintain an optimum efficiency.

S6BP401AJ2SN1B000 is capable of providing a maximum output current of 3A with an accuracy of ±1.8mV and a ripple voltage of ±3mV. It also offers a wide range of safety features, such as overcurrent protection, thermal shutdown and over voltage protection. All these features make S6BP401AJ2SN1B000 an ideal choice for various voltage regulation applications.
