1.8-V to 3.8-V Input Voltage Range
Up to 96% High Efficiency Synchronous
The TPS62510 family are high-efficiency step-down
converters targeted for operation from a 1.8-V to
Step-Down Converter
3.8-V input voltage rail, ideally suited for 2-cell
1.5-MHz Fixed Frequency PWM Operation
Alkaline or NiMHd applications. The TPS62510 is
1% Output Voltage Accuracy in Fixed
also ideal as a point-of-load regulator running from a
Frequency PWM Mode
fixed 3.3-V, 2.5-V or 1.8-V input voltage rail. The
converter operates in fixed frequency PWM mode
Power Save Mode Operation for High
switching at 1.5 MHz with the MODE pin high. Pulling
Efficiency Over the Entire Load Current Range
the MODE pin low enables the high efficiency mode.
22-A Quiescent Current
In high efficiency mode, the device operates with a
Fixed and Adjustable Output Voltage
1.5 MHz fixed frequency PWM at nominal load
current, and automatically enters the Power Save
Output Voltage Tracking (OVT) for Reliable
Mode at light load currents. For maximum system
Sequencing
reliability, the converter features Output Voltage
Available in a 10-Pin QFN (3 x 3 mm) Package
Tracking using the OVT pin to allow sequencing, and
to allow for the output voltage to track an external
voltage applied to this pin.
