FEATURES  
DESCRIPTION  
The LM2731 switching regulators are current-mode  
boost converters operating at fixed frequencies of 1.6  
MHz (“X” option) and 600 kHz (“Y” option).

22V DMOS FET Switch  
•
1.6 MHz (“X”), 0.6 MHz (“Y”) Switching  
Frequency  
The use of SOT-23 package, made possible by the  
minimal power loss of the internal 1.8A switch, and  
use of small inductors and capacitors result in the  
industry's highest power density. The 22V internal  
switch makes these solutions perfect for boosting to  
voltages up to 20V.

•
Low RDS(ON) DMOS FET  
Switch Current up to 1.8A  
Wide Input Voltage Range (2.7V–14V)  
Low Shutdown Current (<1 µA)  
5-Lead SOT-23 Package  
These parts have a logic-level shutdown pin that can  
be used to reduce quiescent current and extend  
battery life.  
Uses Tiny Capacitors and Inductors  
Cycle-by-Cycle Current Limiting  
Internally Compensated  
Protection is provided through cycle-by-cycle current  
limiting and thermal shutdown. Internal compensation  
simplifies design and reduces component count.
