Application field and working principle

The BD9615MUV-LBE2 synchronous buck DC/DC switching regulator is designed for a variety of applications. It is well suited for portable, battery-powered devices, including laptops and tablet computers. The device can be used in systems where the available input voltage is higher than the core power requirements, such as when powering DDR3 memory and microcontrollers. This regulator can also be used in automotive, medical and telecom applications.The BD9615MUV-LBE2 regulator operates by using two transistors to control the power transfer from an input voltage source to an output voltage load. The transistors are connected in a synchronous buck configuration and controlled by an internal digitally controlled oscillator (DCO). The DCO is responsible for setting the frequency of the switching transistors, allowing them to switch at the right time and forcing current through the inductor and into the output load. The regulator is also equipped with a wide range of protections, such as under-voltage lockout, thermal shutdown, output short-circuit protection and over-voltage protection. The BD9615MUV-LBE2 also features a spread spectrum control, which allows the device to reduce radiated electromagnetic interference (EMI).

Conclusion

The BD9615MUV-LBE2 synchronous buck DC/DC switching regulator from ROHM Semiconductor is a high-performance and low-quiescent current switching regulator. It is suitable for a variety of applications and offers a low-voltage output support of up to 0.6 V with a maximum output load of 1.3 A. It provides accurate current regulation, excellent efficiency and has a wide range of protections to ensure safe operation. The device is also equipped with a spread spectrum control, which allows it to reduce radiated EMI levels.
