Product Description

The MP2496 integrates a monolithic, step-down, switch-mode converter with a single USB current-limit switch and charging port identification circuits. The MP2496 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 MP2496 provides a USB dedicated charging port (DCP), which supports battery charging specification 1.2 (BC1.2), divider mode, and 1.2V/1.2V mode, eliminating the need for 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 MP2496 requires a minimal number of readily available, standard, external components and is available in a QFN-26 (4mmx4mm) package.
