The LMR62014 is • Cycle-by-Cycle Current Limiting capable of greater than 90% duty cycle, making it • Internally Compensated ideal for boosting to voltages up to 20V. • 5-Pin SOT-23 Packaging (2.92 x 2.84 x 1.08mm) These parts have a logic-level shutdown pin that can • Fully Enabled for WEBENCH® Power Designer be used to reduce quiescent current and extend battery life. PERFORMANCE BENEFITS Protection is provided through cycle-by-cycle current • Extremely Easy to Use limiting and thermal shutdown. Internal compensation simplifies design and reduces component count. • Tiny Overall Solution Reduces System Cost APPLICATIONS • Boost Conversions from 3.3V, 5V, and 12V Rails • Space Constrained Applications • Embedded Systems • LCD Displays • LED Applications System Performance Efficiency vs Load Current Efficiency vs Load Current VIN = 3.3V, VOUT = 12V VIN = 5V, VOUT = 12V 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SIMPLE SWITCHER, WEBENCH are registered trademarks of Texas Instruments. 3 All other trademarks are the property of their respective owners.
