Overview

LM2594(HV) is a 150 KHz fixed-frequency PWM step-down DC/DC converter capable of driving a 1.5A load, featuring high efficiency, low ripple, and excellent line and load regulation. This regulator requires minimal external components, is easy to use, and integrates internal frequency compensation and a fixed-frequency oscillator. Its PWM control circuit allows linear duty cycle adjustment from 0% to 100%. The device incorporates built-in enable and overcurrent protection functions. When the secondary current limiting function is triggered, the operating frequency reduces from 150 KHz to 50 KHz. The built-in compensation module minimizes the number of external components required.
