3A, 1 Cell Li-Ion Battery Switching Charger With NVDC Power Path Management
The EV2617B-L-00A is an evaluation board for MP2617B, a 3A/1.6MHz 1-cell switching charger with power path management.
MP2617B integrates a synchronous BUCK regulator for powering the system output and charging the battery. For USB mode, the input current limit can be programmed to 450mA and 825mA via the logic pins to cover the USB2.0 and USB3.0. For the adapter input, the input current is also limited to avoid overloading the adapter. The value can be programmed up to 3A.
MP2617B regulates the system voltage for powering the external load and charge the battery simultaneously. When the current limit is hit, the system load is satisfied in priority, the charger will take the leavings to charge the battery. Additionally, the smart power path control will make the charge switch as a connection from battery to the system to supplement power the load if the system requirement increases over the input limited power or the input is removed.
