LM2731XMFX/NOPB

开关稳压器 0.6/1.6 MHz Boost Converters With 22V Internal FET Switch in SOT-23 5-SOT-23 -40 to 125

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 highest power density of the industry. The 22-V internal switch makes these solutions perfect for boosting to voltages up to 20 V.

These parts have a logic-level shutdown pin that can 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.
