产品描述

The MP2496M integrates a monolithic, step-down, switch-mode converter and a single USB current-limit switch with charging port identification circuits. It achieves 2.5A of continuous output current with excellent load and line regulation over a wide input supply range.
The output of the USB switch is current limited. The MP2496M provides a USB dedicated charging port (DCP) which supports battery charging specification 1.2 (BC1.2), divider mode, and 1.2V/1.2V mode without the need of outside user interaction. The output voltage has programmable line-drop compensation.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MP2496M requires a minimum number of readily available, standard, external components and is available in a QFN-26 (4mmx4mm) package.
