DESCRIPTION
The ATI2305 is a 1.5MHz switching frequency step-down
current-mode, DC-DC converter. With excellent stability and
transient response, the constant-frequency PWM control
works well at heavy load. There is a power-saving Pulse-
Skipping Modulation (PSM) mode in the ATI2305 which
can reduce quiescent current under light load operation to
save power and ensure the longest battery life in portable
applications.
The ATI2305 allows input voltages from 2.5V to 5.5V,
allowing the use of a single Li+/Li-polymer cell, multiple
Alkaline/NiMH cell, USB, and other standard power sources.
The output voltage can be adjustable from 0.6V to the input
voltage. The part number suffix ATI2305-XX indicates preset
output voltage of 3.3V, 2.8V, 2.5V, 1.8V, 1.5V, 1.2V or
adjustable. Internal power switch and synchronous rectifier
are used by all versions to minimize external part count and
realize high efficiency. During shutdown, the input is
disconnected from the output and the shutdown current is
less than 0.1μA. Other key features include under-voltage
lockout to prevent deep battery discharge.
Three packages are available for ATI2305: SOT23-5,
DFN2X2 6-Pin and QFN3X3 16-Pin.
