The LM27313 switching regulator is a current-mode boost converter with a fixed operating frequency of 1.6 MHz.
The use of the SOT-23 package, made possible by the minimal losses of the 800 mA switch, and small inductors and capacitors result in extremely high power density. The 30V internal switch makes these solutions perfect for boosting to voltages of 5V to 28V.
This part has a logic-level shutdown pin that can be used to reduce quiescent current and extend battery life.
Protection is provided through cycle-by-cycle current limiting and thermal shutdown. Internal compensation simplifies design and reduces component count.
