The LM2594M-ADJ is a 150 KHz fixed-frequency PWM buck (step-down) DC/DC converter from UMW Youtai Semiconductor. It is designed to drive a 1.5A load with high efficiency, low ripple, and excellent line and load regulation. The device requires a minimum number of external components, featuring internal frequency compensation and a fixed-frequency oscillator.
Key electrical specifications include a wide input voltage range of 4.5V to 40V and an adjustable output voltage from 1.23V to 37V. It has a maximum duty cycle of 100% and a minimum dropout voltage of 1.5V. The switching frequency is fixed at 150kHz, with a reduction to 50kHz when the second current limit function is active. The operating temperature range is -40°C to 125°C (TJ).
This regulator is available in an 8-SOP package, suitable for surface mount applications. Its internal components include an optimized power transistor, thermal shutdown, and current limit functions. Applications include LCD monitors, digital photo frames, set-up boxes, ADSL modems, and telecom/networking equipment.
