LM2674 - SIMPLE SWITCHER Power Converter High Efficiency 500 mA Step-Down Voltage Regulator

Download the LM2674 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same simple switcher power converter high efficiency 500 ma step-down voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2674 series of regulators are monolithic integrated circuits built with a LMDMOS process.

These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500 mA load current with excellent line and load regulation.

Key Features

  • include a guaranteed ± 1.5% tolerance on output voltage within specified input voltages and output load conditions, and ± 10% on the oscillator frequency. External shutdown is included, featuring typically 50 µA stand-by current. The output switch includes current limiting, as well as thermal shutdown for full protection under fault conditions. To simplify the LM2674 buck regulator design procedure, there exists computer design software, LM267X Made Simple. Features n n n n n n n n n n n n n n.

LM2674 SIMPLE SWITCHER Power Converter High Efficiency 500 mA Step-Down Voltage Regulator September 1998 LM2674 SIMPLE SWITCHER ® Power Converter High Efficiency 500 mA Step-Down Voltage Regulator General Description The LM2674 series of regulators are monolithic integrated circuits built with a LMDMOS process. These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500 mA load current with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V, 12V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include patented internal frequency compensation (Patent Nos.
