Usually the feedback pin is connected to a node on a voltage divider which adjusts output to make sure the voltage at the node stays at 1.25V but I would break this connection with a zener diode. When voltage at the output gets to around 12.6V the diode allows a reverse current overriding the current sensor and producing voltage regulation.

But in this case a problem may arise, for example, if you want to charge a 4.2V Li-ion batteries from a 5V supply due to the presence of the protection diode and other small drops across other components. This drop is generally about 1V which makes it very difficult to provide 4.2V to the Li-ion batteries using the buck converter topology.
The considered battery requires a standard charging current of 0.5 A, however the circuit is designed to provide the rapid charge current of 1.3 A as the output by using the buck converter. The converter is operated in continuous conduction mode and helps in charging the battery under constant current mode.
The DC-DC converter uses a combination of buck-boost converter and boost converter mode to charge the Li-ion battery. In case of Li-ion, the constant current constant voltage (CC CV) charging algorithm is used to charge the battery.
In this work, the buck converter is used to attain a high charging current, besides providing the regulated voltage to the battery. Initially, the AC supply obtained from the mains is converted to DC using an AC-DC rectifier. The rectifier output is further fed to the buck converter to increase the output current of the circuit.
The above charger is is intended for charging a single Li-ion or two NiMH in series using a 5V supply input. Details on the implementation are given in AN2390 where you can find results for NiMH batteries as well as for a charger used simply in buck converter mode.
In case of Li-ion, the constant current constant voltage (CC CV) charging algorithm is used to charge the battery. Here we have chosen the input voltage just enough to show the functionality of the converter in buck-boost mode and boost mode.
