General Description Figure 1: Available Products Devices AS1345A AS1345B AS1345C AS1345D 18V, High Efficiency, DC-DC Step-Up Converter The AS1345 high efficiency DC-DC step-up converter contains an internal N-channel and an internal P-channel output isolation switch. The device operates from a 2.9V to 5.0V supply and can boost voltages up to 18V. A hysteretic control scheme is used to provide the highest operating efficiency over a wide range of input and output load conditions. The internal MOSFET switches reduce the external ponent count and a high switching frequency allows the use of tiny surface mount ponents. The AS1345 employ a factory set current limit to reduce...
