1.5-A, LOW V HIGH EFFICIENCY STEP-DOWN CONVERTER

FEATURES

DESCRIPTION

•

1.8-V to 3.8-V Input Voltage Range

The TPS62510 family are high-efficiency step-down

converters targeted for operation from a 1.8-V to

3.8-V input voltage rail, 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 device 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.
