LM2674M-ADJ/NOPBThe LM2674M-ADJ/NOPB is a SIMPLE SWITCHER® 500mA low component count Step-down Regulator, monolithic integrated circuit built with a LMDMOS process. This regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 500mA load current with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation (Patent Nos. 5.382.918 and 5.514.947) and a fixed frequency oscillator. The LM2674 series operates at a switching frequency of 260kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Because of its very high efficiency (>90%), the copper traces on the printed circuit board are the only heat sinking needed. A family of standard inductors for use with the LM2674 are available from several different manufacturers., Efficiency up to 96%, Computer design software (version 6.0), Simple and easy to design, Requires only 5 external components, Uses readily available standard inductors, ±1.5% Maximum output voltage tolerance over line and load conditions, Guaranteed 500mA output load current, 0.25R DMOS output switch, 260kHz Fixed frequency internal oscillator, TTL shutdown capability, low power standby mode, Thermal shutdown and current limit protection, Green product and no Sb/BrМикросхемы / Микросхемы управления питанием / Импульсные преобразователи Корпус: 8-SOIC, инфо: Стаб.напр.импульсный Step-Down 0.5A Uвх=8…40V Uвых=1.2…37V 1.5% -40…+125C
