RT8063
3A, 2MHz, Synchronous Step-Down Converter
General Description
The RT8063 is a high efficiency synchronous, step-down
DC/DC converter. Its input voltage range is from 2.7V to
5.5V and provides an adjustable regulated output voltage
from 0.8V to 5V while delivering up to 3A of output current.
The internal synchronous low on resistance power
switches increase efficiency and eliminate the need for
an external Schottky diode. The default switching
frequency is set at 2MHz, if the RT pin is left open. It can
also be varied from 200kHz to 2MHz by adding an external
resistor. Current mode operation with external
compensation allows the transient response to be
optimized over a wide range of loads and output capacitors.

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may
affect device reliability.
Note 2. θJA is measured at TA = 25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7. θJC is
measured at the exposed pad of the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
