Product Overview

The LTC3455EUF#PBF is a complete Power Management Solution for a variety of portable applications. This device contain two synchronous step-down DC/DC converters, an USB power controller, a full-featured Li-Ion battery charger, a hot swap output, a low-battery indicator and numerous internal protection features. The LTC3455 provide a small, simple solution for obtaining power from three different power sources a single-cell Li-Ion battery, an USB port and a wall adapter. Current drawn from the USB bus is accurately limited under all conditions. Whenever an USB or a wall adapter is present, the battery charger is enabled and all internal power for the device is drawn from the appropriate external power source. All outputs are discharged to ground during shutdown to provide complete output disconnect.
  • Accurate USB current limiting (500/100mA)
  • Two high efficiency DC/DC converters up to 96%
  • Thermal regulation maximizes battery charge rate without risk of overheating
  • Hot swap output for SDIO and memory cards
