DESCRIPTION
The ATI2301 is a step-down current-mode, DC-DC
converter. At heavy load, it works at the constant frequency
PWM mode which has good stability and transient response.
To ensure the longest battery life under light load in portable
applications, the ATI2301 features a power-saving pulseskipping
modulation (PSM) mode, which reduces quiescent
current to save power.
It comes with an internal power switch and a synchronous
rectifier minimizing the external part count with high
efficiency. During shutdown, the input is disconnected from
the output and the shutdown current is less than 0.1 uA. To
prevent battery from being over discharged, it has a undervoltage
lockout circuit, to shut down the converter upon
detecting the input voltage below a preset value.
The ATI2301 has an input voltage from 2.5V to 5.5V,
allowing the use of a single Li+/Li-polymer cell battery,
multiple Alkaline/NiMH cell battery, USB port power, and
other 2.7 to 5V standard power sources. The output voltage
can be set from 0.6V to the input voltage, while the part
number suffix ATI2301-XX indicates a pre-set output
voltage versions: adjustable. The maximum output current
limit is 800mA.
The ATI2301 is available in a compact and easy soldering
SOT23-5 package.
