Description

The LM2733XMFX switching regulators are current-mode boostconverters operating fixed frequency of 1.6 MHz (&ldquo;X&rdquo; option)and 600 kHz (&ldquo;Y&rdquo; option).The use of SOT-23 package, made possible by the minimalpower loss of the internal 1A switch, and use of small induc-tors and capacitors result in the industry&rsquo;s highest powerdensity. The 40V internal switch makes these solutions per-fect for boosting to voltages of 16V or greater.These parts have a logic-level shutdown pin that can beused to reduce quiescent current and extend battery life.Protection is provided through cycle-by-cycle current limitingand thermal shutdown. Internal compensation simplifies de-sign and reduces component count.
