FEATURES  
DESCRIPTION  
The LMR62014 switching regulator is a current-mode  
boost converter operating at fixed frequency of  
1.6 MHz.  
23  
•
Input Voltage Range of 2.7V to 14V  
Output Voltage up to 20V  
•
•
•
•
•
•
•
•
Switch Current up to 1.4A  
The use of SOT-23 package, made possible by the  
minimal power loss of the internal 1.4A switch, and  
use of small inductors and capacitors result in the  
industry's highest power density. The LMR62014 is  
capable of greater than 90% duty cycle, making it  
ideal for boosting to voltages up to 20V.  
1.6 MHz Switching Frequency  
Low Shutdown Iq, <1 µA  
Cycle-by-Cycle Current Limiting  
Internally Compensated  
5-Pin SOT-23 Packaging (2.92 x 2.84 x 1.08mm)  
Fully Enabled for WEBENCH® Power Designer  
These parts have a logic-level shutdown pin that can  
be used to reduce quiescent current and extend  
battery life.  
PERFORMANCE BENEFITS  
Protection is provided through cycle-by-cycle current  
limiting and thermal shutdown. Internal compensation  
simplifies design and reduces component count.

•
Extremely Easy to Use  
Tiny Overall Solution Reduces System Cost  
APPLICATIONS  
•
Boost Conversions from 3.3V, 5V, and 12V
