DESCRIPTION

The LMR62014 switching regulator is a current-mode

boost converter operating at fixed frequency of

1.6 MHz.

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.

These parts have a logic-level shutdown pin that can

be used to reduce quiescent current and extend

battery life.

Protection is provided through cycle-by-cycle current

limiting and thermal shutdown. Internal compensation

simplifies design and reduces component count.
