3 Description
The TPS62992-Q1 is a highly efficient, small, and
flexible synchronous step-down DC-DC converter that
is easy to use. A selectable switching frequency of 2.5
MHz or 1.0 MHz allows the use of small inductors and
provides fast transient response. The device supports
high VOUT accuracy of ± 1.5% across the entire
operasting temperature range and enhanced load
transient performance with the DCS-Control topology.
The wide 3-V to 10-V input voltage range supports a
variety of nominal inputs, like 9-V supply rails, singlecell
or multi-cell Li-Ion, and 5-V or 3.3-V rails.
The TPS62992-Q1 can automatically enter power
save mode (if auto PFM or PWM is selected) at
light loads to maintain high efficiency. Additionally,
to provide high efficiency at very small loads, the
device has a low typical quiescent current of 4 μA.
AEE, if enabled, provides high efficiency across VIN,
VOUT, and load current. The device includes a MODE/
Smart-CONF input to set the internal and external
divider, switching frequency, output voltage discharge,
and automatic power save mode or forced PWM
operation.
