austriamicrosystems introduces the AS1323, a step-up DC-DC converter which comes in a 5-pin TSOT package. The AS1323 delivers 100mA output current from a single AA battery with possible fixed output voltages of 2.7V, 3.0V and 3.3V, operating from an input voltage between 0.75 and 2V. The AS1323 offers an integrated low-voltage boot circuit which ensures start-up even with high load currents. The minimum start-up voltage of 0.95V is independent of the load current. With only 1.6µA quiescent current and a shutdown mode drawing less than 200nA current austriamicrosystems demonstrates continued leadership in power consumption reduction. Furthermore, during shutdown the battery is completely disconnected from the output. Another feature of this device is an internal synchronous rectification which ensures high efficiency and eliminates the need for an external diode. The AS1323 is available in a 5-pin TSOT23 package suitable for the industrial temperature range of -40°C to +85°C.
