The escalating demand for consumer technology and the use of complex digital subsystems have driven PMICs that provide a range of monolithic devices ideal for efficient power management efficiency. The BD95514MUV-E2 is an example of one such device from ROHM – a leading manufacturer of power semiconductors – that provides a wide operating voltage range and output current among other features.

BD95514MUV-E2 - Voltage Regulators - DC DC Switching Regulators

The BD95514MUV-E2 is an integrated switching regulator that provides higher power conversion efficiency than other solutions by utilizing ROHM\'s original “No-PWM” control topology with a constant frequency switching power supply architecture. The device is suitable for applications such as notebook PCs, tablets, digital home appliances, and similar applications requiring high efficiency and stability.

Application Field

The BD95514MUV-E2 is designed for use in a wide range of power conversion applications that require a high efficiency and stable output. The device can supply currents up to 1A and can be used to create a regulated power supply with an output voltage range that can be set between 0.25V and 22V. As such, it can be used in displays, TVs, game consoles, devices with high-speed processors, photocopiers, laser printers, and other office, consumer and industrial applications.

Working Principle

The BD95514MUV-E2 is based on a No-PWM control topology and contains several built-in functions, including a switching control circuit, linear regulator (including overcurrent, overvoltage and thermal shutdown functions), overcurrent protection circuit, driver circuit and a over temperature protection circuit. This allows it to provide the stable and high-efficiency output of 5V, 12V, and 15V without the need for any external components. The device also includes a synchronous rectifier for conversion efficiency optimization, as well as an enable function.

The working of the BD95514MUV-E2 is relatively simple. The device is powered from an unregulated, unregulated DC supply and the DC-DC conversion and output is created by controlling the switching frequency. This allows the switching frequency to be changed depending on each load conditions, resulting in greater control over the output voltage of the device. As such, the BD95514MUV-E2 can maintain an optimum power output regardless of the input voltage or load conditions.

The BD95514MUV-E2 also provides higher efficiency than other solutions. This is achieved through the use of synchronous rectifier and lower switching frequency, which limits switching noise while lowering both the switching power losses and component count. This results in a lower overall system cost and simpler design.

Conclusion

The BD95514MUV-E2 is an integrated switching regulator designed for a broad range of applications, including displays, TVs, game consoles, devices with high-speed processors, photocopiers and laser printers. The device features high efficiency and stability, and also includes built-in functions, overvoltage protection, overcurrent protection, driver circuit, and a over temperature protection circuit, enabling it to provide a regulated power output with an adjustable voltage range between 0.25V and 22V. Additionally, the device provides higher efficiency than conventional solutions, thanks to its synchronous rectifier and lower switching frequency, making it an ideal solution for a variety of power applications.
