FEATURES
DESCRIPTION
The LMR62014 switching regulator is a current-mode
23
• Input Voltage Range of 2.7V to 14V
boost converter operating at fixed frequency of
• Output Voltage up to 20V
1.6 MHz.
• Switch Current up to 1.4A
The use of SOT-23 package, made possible by the
• 1.6 MHz Switching Frequency
minimal power loss of the internal 1.4A switch, and
• Low Shutdown Iq, <1 µA
use of small inductors and capacitors result in the
industry's highest power density. The LMR62014 is
• Cycle-by-Cycle Current Limiting
capable of greater than 90% duty cycle, making it
• Internally Compensated
ideal for boosting to voltages up to 20V.
• 5-Pin SOT-23 Packaging (2.92 x 2.84 x 1.08mm)
These parts have a logic-level shutdown pin that can
• Fully Enabled for WEBENCH
®
Power Designer
be used to reduce quiescent current and extend
battery life.
PERFORMANCE BENEFITS
Protection is provided through cycle-by-cycle current
• Extremely Easy to Use
limiting and thermal shutdown. Internal compensation
simplifies design and reduces component count.
• Tiny Overall Solution Reduces System Cost
APPLICATIONS
• Boost Conversions from 3.3V, 5V, and 12V
Rails
• Space Constrained Applications
• Embedded Systems
• LCD Displays
• LED Applications
