Milpitas, Calif –Linear Technology’s first devices in a new family of complete system-in-a-package µModule battery chargers support an output charge current up to 2A.
The LTM8061 features active input-current management to protect against supply rail droop, while providing maximum charge current to the load. The LTM8062 actively manages the output charge current to maximize the power sourced from a solar cell following Maximum Peak Power Tracking (MPPT) principles.
The LTM8061 is specifically targeted for charging Li-Ion or Li-polymer batteries with float voltages of 4.1V, 4.2V, 8.2V and 8.4V. An externally adjustable float voltage allows the LTM8062 to support charging of single-and multi-cell Li-Ion, Li-polymer, Lithium iron phosphate (LiFePO4) and sealed lead acid (SLA) batteries up to 14.4V.

I would say this part is not targeted for simple cell phone charger. People can easily build a charge with BOM cost lower than $4 but this module idea can help reducing the board space and improve the reliability. I think that's the rationale behind such module approach.
