LM2731 0.6/1.6-MHz Boost Converters With 22-V Internal FET Switch in SOT-23  
1 Features  
3 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).

22-V DMOS FET Switch  
1.6-MHz (X Option), 0.6-MHz (Y Option) Switching  
Frequency  
The use of SOT-23 package, made possible by the  
minimal power loss of the internal 1.8-A switch, and  
use of small inductors and capacitors result in the  
highest power density of the industry. The 22-V  
internal switch makes these solutions perfect for  
boosting to voltages up to 20 V.  
Low RDS(ON) DMOS FET  
Switch Current Up to 1.8 A  
Wide Input Voltage Range (2.7 V to 14 V)  
Low Shutdown Current (<1 µA)  
5-Lead SOT-23 Package  
These parts have a logic-level shutdown pin that can  
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.
