LM2597MX-ADJ Description

LM2597MX-ADJ is a member of the step-down voltage regulator. This monolithic integrated circuit is able to provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5-A load with excellent line and load regulation. Compared with the LM2594 series, it delivers additional supervisory and performance features added. It is simple to use due to a minimum number of external components and is able to deliver internal frequency compensation, improved line, and load specifications, a fixed-frequency oscillator, Shutdown/Soft-start, error flag delay, and error flag output.

LM2597MX-ADJ Features

Specified 0.5-A output current

Input voltage range up to 60 V

150-kHz fixed-frequency internal oscillator

Error output delay

Bias supply Pin (VBS) for internal circuitry
