The AME5145 switching regulator is current-mode boostconverters operating at fixed frequency of 1.6 MHz.The use of SOT-25/TSOT-25, DFN-8(3mmx3mmx0.75mm) & MSOP-8 packages, made possible by theminimal power loss of the internal 1.8A switch, and useof small inductor and capacitors result in the industry'shighest power density. The 30V internal switch makesthese solutions perfect for boosting to voltages up to 30V.These parts have a logic-level shutdown pin that canbe used to reduce quiescent current and extend batterylife. Protection is provided through cycle-by-cycle currentlimiting and thermal shutdown. Internal compensationsimplifies and reduces component count.
