XL2594-ADJ – DC-DC Converter – Xinluda

The XL2594-ADJ from Xinluda is a 0.5A monolithic step-down (buck) switching regulator with a 150kHz fixed-frequency oscillator, input up to 60V, and an adjustable output of 1.2V to 37V in an SOP-8 package.

The XL2594-ADJ is a monolithic step-down (buck) switching voltage regulator from Xinluda Information Technology Co., Ltd. It integrates all of the active functions required for a buck converter, delivering up to 0.5A of output current with excellent line and load regulation. As the adjustable (-ADJ) member of the XL2594 series, it provides a programmable output voltage from 1.2V up to 37V (57V on the high-voltage version), making it a versatile choice for designs that require a non-standard rail. The XL2594 family follows the same SIMPLE SWITCHER-style buck architecture as the industry-standard LM2594; confirm pinout and electrical limits against both datasheets before substituting.

Key Features

• Step-down (buck) switching regulator topology
