130mA Step-Up DC-DC Converter; ■ Fixed Output Voltage: +5.0V\n■ Output Current: Up to 130mA (@ 2V VBATT)\n■ Internal Synchronous Rectifier\n■ Shutdown Mode Supply Current: Less Than 1μA\n■ Efficiency: Up to 96%\n■ Minimum Input Voltage: +1.5V\n■ Accurate Shutdown Low-Battery Cutoff Threshold\n■ Battery Input Connected to Pin OUT in Shutdown Mode for Backup Power\n■ 6-pin SOT23 PackageApplications\n?? The AS1321 is ideal for low-power applications where ultra-small size is critical as in medical \n?? diagnostic equipment, hand-held instruments, pagers, digital cameras, remote wireless \n?? transmitters, cordless phones, and PC cards.\n?? The device is also perfect as a local +5.0V supply or as a battery backup.\n;

General Description\nThe AS1321 is a high-efficiency step-up DC-DC converter designed to generate a fixed output voltage of +5.0V.\nThe 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).\nIn 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.\nThe AS1321 provides a power-on reset output that goes high-impedance when the output reaches 90% of its regulation point.\nThe SHDNN trip threshold of the AS1321 can be used as an input voltage detector that disables the device when the battery voltage falls to a predetermined level.\nAn internal synchronous rectifier is included, which is parallel with the external Schottky diode.\nThe AS1321 is available in a 6-pin SOT23 package.\nKey
