1 / 34 page  LTC3101 1 3101fb TYPICAL APPLICATION FEATURES APPLICATIONS DESCRIPTION Wide VIN, Multi-Output DC/DC Converter and PowerPath Controller The LTC ®3101 is a complete power management solution for low power portable devices. It provides three high efficiency switching DC/DC converters which seamlessly transition from battery to USB/wall adapter power when available. A synchronous buck-boost regulator provides complete flexibility, allowing operation from a single Li-Ion/Polymer battery, 2 to 3 AA cells, a USB port or any other power source operating from 1.8V to 5.5V. Two always-alive outputs, a 50mA LDO and a 200mA MAX output that tracks the higher voltage input supply, provide power for critical functions or additional external regula- tors. Flash memory cards can be directly powered from the protected 100mA Hot Swap output. Pushbutton control logic and a programmable-duration microprocessor reset generator simplify interfacing to a microprocessor while internal sequencing and independent enable pins provide flexible power-up options. The LTC3101 is available in a low profile (0.75mm) 24-lead 4mm × 4mm QFN package.
