ADI LTC3101EUF#PBF

USB, Периферийные устройства380 мкА1,8 В ~ 5,5 В

Overview

The LTC3101EUF 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 regulators. 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 LTC3101EUF is available in a low profile (0.75mm) 24-lead 4mm × 4mm QFN package.
