The LTC4040 is unique in Linear’s portfolio due to its high integration level. The LTC4040 replaces a combination 3-chip solution: a battery charger such as the LTC4001 or LTC4002, a boost switching regulator like the LTC3421, and a PowerPath controller such as the LTC4412 for example. This two-inductor, 3-chip solution will not have equal performance and will also be much larger. The LTC4040‘s high integration level and single inductor requirement allows it to provide a simpler, more compact and full-featured solution.
