LM27313  
1.6 MHz Boost Converter With 30V Internal FET Switch in  
SOT-23  
General Description  
The LM27313 switching regulator is a current-mode boost  
converter with a fixed operating frequency of 1.6 MHz.  
The use of the SOT-23 package, made possible by the mini-  
mal losses of the 800 mA switch, and small inductors and  
capacitors result in extremely high power density. The 30V  
internal switch makes these solutions perfect for boosting to  
voltages of 5V to 28V.  
Features  
30V DMOS FET switch  
1.6 MHz switching frequency  
Low RDS(ON) DMOS FET  
Switch current up to 800 mA  
Wide input voltage range (2.7V–14V)  
Low shutdown current (<1 µA)  
5-Lead SOT-23 package  
This part has a logic-level shutdown pin that can be used to  
reduce quiescent current and extend battery life.  
Uses tiny capacitors and inductors  
Protection is provided through cycle-by-cycle current limiting  
and thermal shutdown. Internal compensation simplifies de-  
sign and reduces component count.  
Cycle-by-cycle current limiting  
Internally compensated  
Applications  
White LED Current Source  
PDA’s and Palm-Top Computers  
Digital Cameras  
Portable Phones, Games and Media Players  
GPS Devices
