SMB137BET-1130V - Brand New TE Connectivity / Alcoswitch IC Chips
-
Description
The SMB137B is a programmable single-cell lithium-ion/lithium polymer battery charger designed for a variety of portable applications. The device provides a simple and efficient way to charge high-capacity Li-Ion batteries via a USB or AC adapter input. Unlike conventional charging devices, the SMB137B’s high-efficiency switch-mode operation eliminates the low charge current and thermal problems of conventional linear solutions. In addition, the switching architecture in conjunction with programmability enables dramatically faster charging– TurboCharge™ mode - from current limited in puts such as USB.
