General Description
The RT5710A is a high efficiency synchronous
step-down DC-DC converter. Its input voltage range is
from 2.5V to 6V and provides an adjustable regulated
output voltage from 0.6V to 3.4V while delivering up to
1A of output current.
The internal synchronous low on-resistance power
switches increase efficiency and eliminate the need for
an external Schottky diode. The Current Mode
Constant-On-time (CMCOT) operation with internal
compensation allows the transient response to be
optimized over a wide range of loads and output
capacitors.
