Data Sheet  
AS1320  
200mA Step-Up DC-DC Converter  
1 General Description  
2 Key Features  
The AS1320 is a high-efficiency step-up DC-DC con-  
verter designed to generate a fixed voltage of +3.3V.  
Fixed Output Voltage: 3.3V  
Output Current: Up to 200mA (@ 2V)  
Internal Synchronous Rectifier  
The AS1320 achieves an efficiency of up to 90%. The  
minimum input voltage is 1.5V, the output voltage is  
fixed at 3.3V, and output current is up to 200mA (@ 2V).  
Requires No External Schottky Diode or FETs  
Shutdown Mode Supply Current: Less Than 1µA  
Efficiency: Up to 90%  
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.  
The AS1320 provides a power-on reset output that goes  
high-impedance when the output reaches 90% of its reg-  
ulation point.  
Minimum Input Voltage: +1.5V  
Accurate Shutdown Low-Battery Cutoff Threshold  
The SHDNN trip threshold of the AS1320 can be used  
as an input voltage detector that disables the device  
when the battery voltage falls to a predetermined level.  
Battery Input Connected to Pin OUT in Shutdown  
Mode for Backup Power  
An internal synchronous rectifier is included, thus an  
external transistor or Schottky diode is not required.  
6-pin SOT23 Package  
The AS1320 is available in a 6-pin SOT23 package.  
3 Applications  
The AS1320 is ideal for low-power applications where  
ultra-small size is critical as in medical diagnostic equip-  
ment, hand-held instruments, pagers, digital cameras,  
remote wireless transmitters, cordless phones, and PC  
cards.  
The device is also perfect as a local 3.3V supply or as a  
battery backup.
