Unterpremstaetten, Austriaaustriamicrosystems expanded its DC-DC converter portfolio with the AS1341, a hysteretic high efficiency 20V step-down regulator that boosts battery life in portable applications.
The AS1341 DC-DC regulator delivers 600mA at 5.0V from a 12V input and can provide adjustable output voltages in the range of 1.25V to VIN or fixed 5V. The device operates from an input voltage of between 4.5 and 20V and offers a high efficiency rate of up to 96%. Additionally, an integrated 100% duty-cycle mode improves efficiency in low dropout conditions.
The AS1341 DC-DC converter allows the use of tiny low profile inductors and small capacitors. Its built-in current limit function can be set to 0.7 or 1.4A switching current for optimizing the converter to the used inductor and load. The AS1341's low quiescent current of 12µA improves light load efficiency and conserves battery life. During shutdown the current draw is reduced to 0.8µA.
The AS1341 DC-DC converter is available now in a 3x3mm TDFN 8-pin package and is specified for the industrial temperature range of -40°C to +85°C.
