... The AS1320 achieves an efficiency 90%. The minimum input voltage is 1.5V, the output voltage is fixed at 3.3V, and output current 200mA (@ 2V). In order to save power the AS1320 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 ...

... AS132 0 Data Sheet Low-Battery Cutoff The AS1320 SHDNN trip threshold (1.228V) can be used as an input voltage detector that disables the device when the battery input voltage falls to a pre-set level. An external resistor-divider network can be used to set the battery- detection voltage (see Figure 15) ...

... Application Information Inductor Selection The control circuitry of the AS1320 permits a wide range of inductor values to be selected – from 4.7 to 47µH; 10µH is ideal for most applications. The intended application should dictate the value of L. The trade-off between required PCB surface area and desired output ripple are the determining factors: smaller values for L require less PCB space, larger values of L reduce output ripple ...
