Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP2151GQFU-P

The MP2151GQFU-P is a synchronous step-down DC-DC converter designed to deliver up to 1A of output current from a wide input voltage range of 2.5V to 5.5V. It features a low quiescent current of 25OºA and operates at a switching frequency of 1.1MHz, which helps in achieving efficient power conversion. The output voltage is adjustable down to 0.6V, making it suitable for various applications including wireless networking cards, portable instruments, and battery-powered devices. This regulator includes several protection features such as output over-voltage protection (OVP) and short-circuit protection (SCP) with hiccup mode, ensuring reliable operation in demanding environments. The device is available in ultra-small SOT563 or UTQFN packages, facilitating integration into compact designs. The MP2151GQFU-P is particularly advantageous for applications requiring low power consumption and high efficiency.
