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 1-A switch 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 or greater.
