... µ General Description The AS1323 high-efficiency step-up DC-DC converter was designed specifically for single-cell, battery-pow- ered devices where lowest quiescent current and high efficiency are essential. The compact device is available in three fixed-voltage variations and is perfect for a wide variety of applications where extremely-low quiescent currents and very-small form factors are critical ...

... Datasheet - Detailed Description The AS1323 is a compact, high-efficiency, step-up DC-DC converter guaranteed to start up with voltages as low as 0.95V, and operate with an input voltage down to 0.75V. Consuming only 1.6µA of quiescent current, the device includes an integrated synchronous rectifier that eliminates the need for an external diode and improves overall effi- ...

... Datasheet - Application Information Figure 20. Typical Application Inductor Selection The control scheme of the AS1323 allows for a wide range if inductor values. A 10µH inductor should be sufficient for most applications (see Figure 20). Smaller inductance values typically offer smaller physical size for a given series resistance, allowing the smallest over- all circuit dimensions ...

... PC Board Layout Considerations The AS1323 has been specially designed to be tolerant to PC board parasitic inductances and resistances. However, to achieve maximum efficiency a careful PC board layout and component selection is vital. Note: For the optimal performance the IC’s VSS and the ground leads of the input and output capacitors must be kept less than 5mm apart using a ground plane ...
