DESCRIPTION

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.
