製品説明

The MP2276 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution that achieves up to 8A of continuous output current with excellent load and line regulation over a wide input supply range. The MP2276 operates at high efficiency over a wide output current load range.

The MP2276 uses constant-on-time (COT) control for fast transient response and eased loop stabilization. Output voltage start-up is controlled by an internal 1.7ms timer, which can be increased by adding a capacitor on SS/TRK. An open-drain power good (PG) signal indicates when the output is within its nominal voltage range.

Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP).

The MP2276 requires a minimal number of readily available, standard external components, and is available in a QFN-14 (2mmx3mm) package.
