com a u s t ri a m i c r o s y s t e m s AS1321 1 3 0 m A St e p - U p D C - D C C o n v e r t e r D a ta S he e t 1 General Description The AS1321 is a high-efficiency step-up DC-DC converter designed to generate a fixed output voltage of +5.
0V.
The AS1321 achieves an efficiency of up to 96%.
The minimum input voltage is +1.
5V, the output voltage is fixed at +5.
0V, and output current is up to 130mA (@ 2V VBATT).
In order to save power the AS1321 features a shutdown mode, where it draws less than 1µA.
In shutdown mode the battery is connected directly to the output enabling the supply of real-time-clocks.
The AS1321 provides a power-on reset output that goes high-impedance ...
