LTC4089/-5 Evaluation Kits
Linear Technology Inc.
Description
Demonstration circuit DC929A-A/B is a monolithic high voltage (6V-36V) switching buck regulator, USB Powerpath controller, and Li-Ion battery charger. It is based on the LTC4089/-5 and provides the following functions: 1.2A monolithic buck regulator with output voltage tracking battery voltage VBAT, a 700mA CC/CV timer terminated temperature qualified charger suitable for Li-Ion cells, a USB power manager that insures compliance with the USB power specification and Powerpath management for the battery. The LTC4089/-5 uses the intermediate bus voltage topology that results in faster charging and lower power loss than the charger fed topology. All this functionality consumes less than 2cm2 of PCB area with all components on one side of the PCB.
