TI TPS2500 and TPS2501 Provide Power for USB

Posted: 11/24/2009 1:34:06 PM
Summary: Texas Instruments has introduced two integrated products designed to provide power and protection for USB ports. The TPS2500 and TPS2501 incorporate a boost switching regulator with an onboard current-limiting switch that saves space and cost by providing an integrated solution that meets 5 V USB power requirements from a 1,8–5,25 V input.

Texas Instruments has introduced two integrated products designed to provide power and protection for USB ports. The TPS2500 and TPS2501 incorporate a boost switching regulator with an onboard current-limiting switch that saves space and cost by providing an integrated solution that meets 5 V USB power requirements from a 1,8–5,25 V input. The output current limit can be programmed via an external resistor from as low as 130 mA to as high as 1400 mA, supporting up to two USB ports from a single device. The onboard switching regulator is a highly efficient synchronous boost converter, with greater than 94% efficiency for 3,3 V inputs at typical USB current ranges. The TPS2500 features a pulse-skipping mode for high efficiency at light loads, while the TPS2501 employs fixed-frequency operation across the load range for EMI sensitive designs.
