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

•

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
