Description
The LM2733 switching regulators are current-mode boost converters operating fixed frequency of 1.6 MHz (“X” option) and 600 kHz (“Y” option).
The use of SOT-23 package, made possible by the minimal power loss of the internal 1-A switch, and use of small inductors and capacitors result in the industrys highest power density. The 40-V internal switch makes these solutions perfect for boosting to voltages of 16 V or greater.
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.

Features
• 40-V DMOS FET Switch
• 1.6 MHz (“X”), 0.6 MHz (“Y”) Switching Frequency
• Low RDS(ON) DMOS FET
• Switch Current up to 1A
• Wide Input Voltage Range (2.7 V – 14 V)
• Low Shutdown Current (< 1 µA)
• 5-Lead SOT-23 Package
• Uses Tiny Capacitors and Inductors
• Cycle-by-Cycle Current Limiting
• Internally Compensated

Applications
• White LED Current Source
• PDA’s and Palm-Top Computers
• Digital Cameras
• Portable Phones and Games
• Local Boost Regulator
