The 30V internal switch makes these solutions perfect for boosting to voltages of 5V to • Switch Current up to 800 mA 28V. • Wide Input Voltage Range (2.7V–14V) This part has a logic-level shutdown pin that can be • Low Shutdown Current (<1 µA) used to reduce quiescent current and extend battery • 5-Lead SOT-23 Package life. • Uses Tiny Capacitors and Inductors Protection is provided through cycle-by-cycle current • Cycle-by-Cycle Current Limiting limiting and thermal shutdown. Internal compensation • Internally Compensated simplifies design and reduces component count. APPLICATIONS • White LED Current Source • PDA’s and Palm-Top Computers • Digital Cameras • Portable Phones, Games and Media Players • GPS Devices Typical Application Circuits 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 All trademarks are the property of their respective owners.
