LM2731 Datasheet 0.6/1.6 Mhz Boost Converters

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM2731 0.6/1.6 MHz Boost Converters With 22V Internal FET Switch in SOT-23 July 2003 LM2731 0.6/1.

General Description

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 industry’s highest power density.

The 22V internal switch makes these solutions perfect for boosting to voltages up to 20V.
