BD9B500MUV is a synchronous buck DC/DC converter designed to operate with an input voltage range of 2.7V to 5.5V and can deliver a maximum output current of 5A. It features integrated low on-resistance power MOSFETs, which contribute to its efficiency. The device employs a constant on-time control system, allowing for fast transient response and high oscillating frequency, typically at 2MHz or 1MHz, depending on configuration. The converter supports an output voltage range from 0.8V to 0.8 times the input voltage. It includes several protection features such as overcurrent protection, short circuit protection, thermal shutdown, and under voltage lockout. The package dimensions are 3.00 mm x 3.00 mm x 1.00 mm, and it is suitable for applications including step-down power supplies for DSPs, FPGAs, microprocessors, and various consumer electronics.
BD9B500MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 5A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal standby power consumption.
