3 Description
The TPS62902-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 operating temperature range and enhanced
load transient performance with the DCS-Control
topology. The wide 3-V to 18-V input voltage range
supports a variety of nominal inputs, like 12-V supply
rails, single-cell or multi-cell Li-Ion, and 5-V or 3.3-V
rails.
The TPS62902-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.
