Description:

0.6/1.6 mhz boost converters.

LM2731, 0.6/1.6 MHz Boost Converters

The LM2731 switching regulators are current-mode boost converters operating at fixed frequencies of 1.6 MHz (“X” option) and 600 kHz (“Y” option).

The use of SOT-23 package, made possible by the minimal power loss of the internal 1.8A switch, and use of small inductors and capacitors result in the i
