1 General Description
The AS1310 is an ultra low I Q hysteretic step-up DC-DC converter
optimized for light loads (60mA), where it achieves efficiencies of up
to 92%.
AS1310 operates from a 0.7V to 3.6V supply and supports output
voltages between 1.8V and 3.3V. Besides the available AS1310
standard variants any variant with output voltages in 50mV steps are
available. See Ordering Information on page 18 for more information.
If the input voltage exceeds the output voltage the device is in a
feed-through mode and the input is directly connected to the output
voltage.
In light load operation, the device enters a sleep mode when most of
the internal operating blocks are turned off in order to save power.
This mode is active approximately 50μs after a current pulse
provided that the output is in regulation.
In order to save power the AS1310 features a shutdown mode,
where it draws less than 100nA. During shutdown mode the battery
is disconnected from the output.
The AS1310 also offers adjustable low battery detection. If the
battery voltage decreases below the threshold defined by two
external resistors on pin LBI, the LBO output is pulled to logic low.
The AS1310 is available in a TDFN (2x2) 8-pin package.
