Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP1567DQ-LF-P

The MP1567DQ-LF-P is a 1.2A DC to DC buck switching regulator designed for low voltage applications with a wide input voltage range of 2.6V to 6V. It features synchronous rectification, achieving over 90% efficiency, which helps to minimize heat generation in compact designs. The regulator can provide output voltages as low as 0.9V, making it suitable for various applications including handheld devices, routers, and digital cameras. The device includes essential protection features such as cycle-by-cycle current limiting, under voltage lockout, and thermal shutdown. It operates at a switching frequency of 800KHz, allowing for smaller external components and reduced board space. The MP1567DQ is available in a compact 10-pin QFN package, which is advantageous for space-constrained applications. Evaluation boards are also available for testing and integration purposes.
