GENERAL DESCRIPTION
Figure 1: Available Products Devices AS1345A AS1345B AS1345C AS1345D AS1345 18V, High Efficiency, DC-DC Step-Up Converter A hysteretic control scheme is used to provide the highest operating efficiency over a wide range of input and output load conditions. The AS1345 employ a factory set current limit to reduce ripple and external component size in low output current applications. With a 500mA current limit the AS1345 is capable of providing 20mA @ 18V output. Peak Coil Current 100mA 200mA 350mA 500mA Output adjustable or fixed adjustable or fixed adjustable or fixed adjustable or fixed For order related information, please refer to “Ordering & Contact Information” on page 26. Built-in safety features protect the internal switches and output components from fault conditions. Additional power-saving attributes include a very low quiescent current and a true shutdown mode.
