AS1310 Step-Up DC/DC Converter

ams DC/DC step-up with ultra low 1µA quiescent current

ams AS1310 Step-Up DC/DC Converter ams' AS1310 is an ultra low quiescent current and hysteretic step-up DC-DC converter optimized for light loads (60mA), which achieves efficiencies of up to 92%. The 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. 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 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 features adjustable low battery detection.
