LM2594 - SIMPLE SWITCHER Power Converter 150 kHz 0.5A Step-Down Voltage Regulator

Download the LM2594 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same simple switcher power converter 150 khz 0.5a step-down voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2594/LM2594HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation.

Key Features

  • include a guaranteed ± 4% tolerance on output voltage under all conditions of input voltage and output load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 85 µA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. The LM2594HV is for.
