    Hi

    The above mentioned part has many features that will make finding an exact match a little difficult. Most of these features though are typically not really needed in the application space. I would recommend you to determine what you really need and search for that. This will help you find the simplest solution which is generally the easiest to design and the lowest cost.

    You may be able to use one of the TPS65217 or LP3971 as is. For the LP3971 you can pair with a battery charger. But, if you can't get the voltages you need then the TPS650244 can handle the currents on the bucks and are externally set Vout voltages. A battery charger is still needed to be paired with the TPS650244.
