ROHM Semiconductor USA, LLC PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - BD9141MUV-E2 BD9141MUV-E2

The BD9141MUV-E2 is a synchronous buck converter designed for high efficiency in step-down voltage regulation. It operates within an input voltage range of 4.5V to 13.2V and can deliver an output current of up to 2A. The output voltage can be adjusted between 2.5V and 6.0V, making it suitable for various applications, including powering LSI devices such as DSPs, microcomputers, and ASICs. This regulator features pulse skip control technology and synchronous rectification, which contribute to its high efficiency across all load ranges. It also incorporates current mode PWM control for fast transient response to load changes. Additional features include a soft-start function, thermal shutdown, under-voltage lockout (UVLO), and short-circuit protection with a time delay function. The device operates within a temperature range of -40¬8C to +105¬8C and comes in a compact VQFN020V4040 package measuring 4.00mm x 4.00mm x 1.00mm. Engineers considering this product should note its low standby current of 0OºA and typical switching frequency of 500kHz, which may be advantageous for power-sensitive applications.
