AS1313

Ultra Low Quiescent Current, DC-DC

Step Down Converter

The AS1313 is an ultra-low quiescent current hysteretic

step-down DC-DC converter optimized for light loads and with

efficiencies of up to 95%.

AS1313 operates from a 2.4V to 5.5V supply and supports

output voltages between 1.2V and 3.6V. Besides the available

AS1313 standard variants, any variant with output voltages in

50mV steps are available.

In order to save power the AS1313 features a shutdown mode,

where it draws less than 100nA. During shutdown mode the

battery is disconnected from the output.

In light load operation, the device enters an idle mode when

most of the internal operating blocks are turned off in order to

save power. This mode is active approximately 100μs after a

current pulse provided that the output is in regulation. The

capacitor connected to the REF pin is an essential part of this

feature.

The AS1313 is available in an 8-pin MLPD (2mm x 2mm) and a

6-pin WL-CSP (0.4mm pitch).

Ordering Information and Content Guide appear at end of

datasheet.
