3 Description

The TPS62903-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 TPS62903-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.
