Introduction
The LTC3569 is a compact power solution for handheld devices. Its tiny 3mm × 3mm QFN package includes three buck regulators with individually programmable output voltages. One regulator supports load currents up to 1200mA, while the other two support currents to 600mA. Two regulators can be paralleled for increased load capability. Each current mode regulator is internally compensated with excellent load and line regulation. A complete 2- or 3-output solution requires a minimum ...
