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.EMI Reduction Technique Wide 7V to 36V Operating Input Voltage Range Fixed 5V Output Voltage with Line Drop Compensation Accurate USB Output Current Limit 40mO/32mO Low-RDS(ON) Internal Buck Power MOSFETs 24mO Low-RDS(ON) Internal USB Power MOSFET 350kHz/250kHz/150kHz Frequency Selectable Programmable Line Drop Compensation Output Over-Voltage Protection (OVP) Hiccup Current Limit Supports DCP Scheme for BC1.2, Divider Mode, and 1.2V/1.2V Mode ±8kV HBM ESD Rating for USB, DP, and DM Available in a QFN-26 (4mmx4mm) Package
