AAT1275 | Boost Converter With USB Power Switch

The AAT1275 SwitchReg is a 2MHz, 500mA synchronous boost converter with an integrated current-limiting load Switch controlled output. The AAT1275 operates from a single-cell Lithium-ion/ polymer battery source and provides a regulated 5V, current limit controlled output to support USB port VBUS applications in portable consumer electronic products. The AAT1275 CAN support a USB 2.0 host port and USB on-the-go operation, as well as general purpose applications where a 5V supply with a user programmable current limit is needed. The high efficiency boost converter section of the AAT1275 is typically set for a 5V output and CAN deliver up to 500mA load current to support USB VBUS operation from an input supply as low as 2.7V. The high boost converter switching frequency (up to 2.0MHz) provides fast load transient and allows the use of small external components. Fully integrated control circuitry simplifies system design and reduces total solution size. The integrated, programmable current limiting load Switch provides USB port protection for portable devices allowing the AAT1275 to supply a 5V USB VBUS up to 500mA. The load Switch provides an active low fault flag to alert the system in the event of an over-current condition applied to the AAT1275 output. The AAT1275 is available in the Pb-free, space-saving 12-pin TSOPJW and 16-pin TDFN34 packages and is rated over the -40C to +85C operating temperature range.
