The AS1321 is a step-up DC-DC converter from Austria Micro Systems, engineered for applications requiring a stable +5.0V output from a lower input voltage. It boasts high efficiency, reaching up to 96%, and can deliver an output current of up to 130mA when operating from a 2V battery.
Key features include a minimum input voltage of +1.5V and a low shutdown mode supply current of less than 1µA. In shutdown mode, the battery is directly connected to the output, enabling real-time clock functionality. The device also provides a power-on reset output that goes high-impedance when the output reaches 90% of its regulation point. The SHDNN input can function as an accurate low-battery cutoff threshold.
This converter is suitable for low-power applications where size is critical, such as medical diagnostic equipment, hand-held instruments, pagers, digital cameras, and PC cards. It is available in a compact 6-pin SOT23 package, ideal for space-constrained designs. The AS1321 is well-suited for use as a local +5.0V supply or as a battery backup solution.
