XL2594-12 – DC-DC Converter – Xinluda

The XL2594-12 from Xinluda is a 150-kHz, 0.5-A monolithic step-down (buck) switching voltage regulator with a fixed 12 V output in an SOP-8 package, requiring only four external components.

The XL2594-12 is a member of Xinluda’s XL2594xx SIMPLE SWITCHER family of monolithic step-down (buck) switching voltage regulators. It integrates all of the active functions needed for a buck regulator capable of driving a 0.5-A load with excellent line and load regulation. The “-12” suffix denotes the factory-fixed 12 V output version; the same family is also offered in 3.3 V, 5 V, and adjustable (ADJ) variants. With an internal 150-kHz fixed-frequency oscillator and internal frequency compensation, the XL2594-12 requires only four external components, making it a simple, space-efficient choice for fixed 12 V rails.

Key Features

• Fixed 12 V output (-12 version of the XL2594xx series)
• Ensured 0.5-A output current
• Input voltage range up to 40 V (recommended operating supply 4.5 V to 40 V)
• 150-kHz fixed-frequency internal oscillator
• Requires only four external components
• Internal frequency compensation
• TTL shutdown capability via ON/OFF pin (low-power standby mode, I_Q typically 85 uA)
• Two-stage frequency-reducing current-limit protection and thermal (overtemperature) shutdown
• Typical efficiency of 88% (V_IN = 25 V, I_LOAD = 0.5 A) for the 12 V version
• ±4% output voltage tolerance over line and load; uses readily available standard inductors
• SOP-8 surface-mount package

Applications

• Simple high-efficiency step-down (buck) regulators for 12 V rails
• On-card / point-of-load switching regulators
• Efficient pre-regulator ahead of linear regulators
• Industrial control, home appliance, and new-energy power supplies
• Positive-to-negative converter topologies

Why Source XL2594-12 from Pacific Component Xchange

The XL2594-12 is a Xinluda-branded part with little to no authorized-distributor stock in Western markets, which makes it difficult to source through mainstream channels.
