LM2733 0.6/1.6 MHz Boost Converters With 40V Internal FET Switch in SOT-23 February 2003 LM2733 0.6/1.6 MHz Boost Converters With 40V Internal FET Switch in SOT-23 General Description The LM2733 switching regulators are current-mode boost converters operating fixed frequency of 1.6 MHz (“X” option) and 600 kHz (“Y” option). The use of SOT-23 package, made possible by the minimal power loss of the internal 1A switch, and use of small inductors and capacitors result in the industry’s highest power density. The 40V internal switch makes these solutions perfect for boosting to voltages of 16V or greater. These parts have a logic-level shutdown pin that can be used to reduce quiescent current and extend battery life.
