Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP2386GG-P

The MP2386GG-P is a synchronous buck converter designed for high efficiency and compact applications. It operates over a wide input voltage range of 4.5V to 24V and can deliver up to 8A of continuous output current. The device features a low quiescent current of 105OºA, making it suitable for battery-powered applications. It employs adaptive constant-on-time control for fast transient response and includes a DC auto-tune loop for improved load and line regulation. The MP2386GG-P integrates low RDS(ON) internal power MOSFETs and utilizes a proprietary switching loss reduction technique to enhance efficiency. Protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown with auto-retry capabilities. The device is packaged in a compact QFN-11 (2mm x 2mm) format, requiring minimal external components, and is stable with both POSCAP and ceramic capacitors. Typical applications include security cameras, portable devices, digital set-top boxes, and flat-panel televisions.
