DescriptionThe LM2733XMF/NOPB switching regulators are current-mode boost converters operating fixedfrequency 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 1-Aswitch and use of small inductors and capacitors, results in the industry’s highest power density.The 40-V internal switch makes these solutions perfect for boosting to voltages of 16 V orgreater.
These parts have a logic-level shutdown pin that can be used to reduce quiescent currentand extend battery life.
Protection is provided through cycle-by-cycle current limiting and thermal shutdown.Internal compensation simplifies design and reduces component count.
