DESCRIPTION

The LMR64010 switching regulators is a current-

mode boost converter operating at a fixed frequency

of 1.6 MHz.

The use of SOT-23 package, made possible by the

minimal power loss of the internal 1A switch, and use

of small inductors and capacitors result in the

industry's highest power density. The 40V internal

switch makes these solutions perfect for boosting to

voltages of 16V or greater.

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.
