Dallas, Tex. — Texas Instruments Inc. (TI) claims the smallest 2.25-MHz DC/DC converter in a 10-pin, 2.5 x 2.5-mm SON package for USB-powered portable applications and wireless modems.
The TPS62750 is a 92-percent power-efficient, synchronous step-down converter, which can provide up to 1-A typical input current. The device supports an input voltage from 2.9 V to 6 V, allowing it to support batteries with an extended voltage range and USB-compliant power requirements.
The device’s unique Power Save Mode operates at light load currents over the entire load current range. In addition, the converter can discharge during shutdown. Other key specifications include +/-10 percent current accuracy and programmable average current limiting for USB applications (50 mA to 300 mA for low current; 0.3 A to 1.3 A for high current). It also provides input voltage monitoring to prevent the USB host from crashing and hot plug, load disconnect, short circuit (Vin/Vout) protection.
Pricing: $1.20 in quantities of 1,000.
Availability: The TPS62750 is available in volume in a 10-pin, 2.5 x 2.5-mm SON package.
