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.

4.95V to 32VDC (40V Abs Max) operating input voltage range
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.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
