Product Summary
The LTC4006EGN-4#TR is a complete constant-current/constantvoltage charger controller for 2-, 3- or 4-cell lithium batteries in a small package using few external components. The LTC4006EGN-4#TR is a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. The applications of the LTC4006EGN-4#TR are (1)notebook computers; (2)portable instruments; (3)battery-backup systems; (4)standalone li-iochargers.
