LM2731 Datasheet (Texas Instruments)

LM2731, 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 1.8-A switch, and use of small inductors and capacitors result in the high
