AS1312 is Hysteretic DC-DC Step-up Converter manufactured by ams.
Ultra Low Quiescent Current, Hysteretic DC-DC Step-up Converter
General Description
The AS1312 is an ultra low IQ hysteretic step-up DC-DC converter.
The AS1312 achieves an efficiency of up to 94% and is designed to operate from a +0.7V to +5.0V supply, the output voltage is fixed in 50mV steps from +2.5V to 5.0V.
In order to save power the AS1312 Features a shutdown mode, where it draws less than 100nA. In shutdown mode the battery is not connected to the output.
If the input voltage exceeds the output voltage the device is in a feedthrough 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...
