TPS62510DRCT

The TPS62510 family are high-efficiency step-down converters targeted for operation from a 1.8-V to 3.8-V input voltage rail, TPS62510DRCT is ideally suited for 2-cell Alkaline or NiMHd applications. The TPS62510 is also ideal as a point-of-load regulator running from a fixed 3.3-V, 2.5-V or 1.8-V input voltage rail. The converter operates in fixed frequency PWM mode switching at 1.5 MHz with the MODE pin high. Pulling the MODE pin low enables the high efficiency mode. In high efficiency mode, the TPS62510DRCT operates with a 1.5 MHz fixed frequency PWM at nominal load current, and automatically enters the Power Save Mode at light load currents. For maximum system reliability, the converter features Output Voltage Tracking using the OVT pin to allow sequencing, and to allow for the output voltage to track an external voltage applied to this pin.

The features of TPS62510DRCT are (1) 1.8-V to 3.8-V Input Voltage Range, (2)1% Output Voltage Accuracy in Fixed Frequency PWM Mode, (3) Up to 96% High Efficiency Synchronous Step-Down Converter, (4) 1.5-MHz Fixed Frequency PWM Operation, (5) Power Save Mode Operation for High Efficiency Over the Entire Load Current Range, (6) Fixed and Adjustable Output Voltage, (7) Output Voltage Tracking (OVT) for Reliable Sequencing, (8) Available in a 10-Pin QFN (3 x 3 mm) Package, (9) 22-µA Quiescent Current. And it can be used in portable devices (mobile phone, PDA), 2-cell NiMHd/Alkaline applications, hard disc drives, point-of-load regulation, notebook computers WiMAX and WLAN applications.
