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.
