XL2594-5.0 – DC-DC Converter – Xinluda

About this part

The XL2594-5.0 from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.) is a monolithic step-down (buck) switching regulator that provides all the active functions needed for a high-efficiency, fixed 5.0 V output power supply. Operating at a 150 kHz fixed switching frequency, it is capable of driving loads up to 0.5 A with excellent line and load regulation while requiring only a minimal number of external components.

The XL2594 family is offered in fixed-output versions plus an adjustable (ADJ) version. The “-5.0” suffix identifies the factory-set 5.0 V fixed-output variant, eliminating the need for an external feedback divider. The device integrates thermal-shutdown and current-limit protection for robust, reliable operation. Its architecture and naming follow the widely used LM2594-class 150 kHz, 0.5 A buck regulator family.

Key Features

• Fixed 5.0 V regulated output (factory-set; no external feedback divider required)
• 150 kHz fixed-frequency internal oscillator, allowing smaller filter components
• 0.5 A output load capability
• Step-down (buck) switching topology with excellent line and load regulation
• Minimal external component count for a compact PCB footprint
• Built-in thermal-shutdown and current-limit protection
• Member of the XL2594 series (fixed and adjustable output options)
• 8-pin SOIC-8 / SOP-8 surface-mount package (PDIP-8 also referenced in the family datasheet)

Applications

• On-board point-of-load 5 V power rails
• Simple, efficient replacements for linear regulators
• Consumer electronics and home appliances
• Industrial control and instrumentation
• Battery-powered and distributed-supply systems
• Set-top boxes, networking, and embedded modules
