LTC1473IGN Datasheet - Linear Technology

DESCRIPTION
The LTC®1473 provides a power management solution for single and dual battery notebook computers and other portable equipment. The LTC1473 drives two sets of back-to-back N-channel MOSFET switches to route power to the input of the main system switching regulator. An internal boost regulator provides the voltage to fully enhance the logic level N-channel MOSFET switches.
