The use of the SOT-23 package, made possible by the minimal losses of the 800-m A switch, and the small inductors and capacitors result in extremely high power density. The 30-V internal switch makes these solutions perfect for boosting to voltages of 5 V to 28 V. This device 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 pensation simplifies design and reduces ponent count. 2 Applications - White LED Current Source - PDAs and Palm-Top...
