Description
The LMR62014XMF/NOPB switching regulator is a current-mode boost converter operating at fixed frequency of1.6 MHz.
The use of SOT-23 package, made possible by the minimal power loss of the internal 1.4A switch, and use of small inductors and capacitors result in the industry's highest power density. The LMR62014XMF/NOPB is capable of greater than 90% duty cycle, making it ideal for boosting to voltages up to 20V.
These parts have 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.
