XH2576-12 – DC-DC Converter – Xinluda

The Xinluda XH2576-12 is a fixed 12V, 3A step-down (buck) switching regulator in a TO-263-5 package, part of the LM2576-compatible XH2576 series. Available for RFQ at Pacific Component Xchange.

The Xinluda XH2576-12 is a monolithic step-down (buck) switching regulator that delivers a fixed 12V output at up to 3A of load current with good line and load regulation. Part of the XH2576 series, it provides a high-efficiency alternative to popular three-terminal linear regulators, substantially reducing heat-sink size and, in many designs, eliminating the heat sink entirely. The XH2576-12 belongs to an LM2576-12-compatible family, making it a convenient option for common buck-regulator designs.

Requiring a minimum of external components, the device integrates internal frequency compensation and a fixed-frequency oscillator, simplifying board design and reducing bill-of-materials cost. Built-in protection features keep the regulator robust under fault conditions.

Key Features

• Fixed 12V output voltage
• Specified 3A output current
• 52 kHz fixed-frequency internal oscillator
• Output voltage tolerance of ±4% under specified line and load conditions
• Wide operating input voltage range (approximately 6V to 40V)
• Cycle-by-cycle current limiting
• Thermal shutdown protection
• External shutdown capability with low-power standby mode (50 µA typical standby current)
• Internal frequency compensation and fixed-frequency oscillator
• TO-263-5 surface-mount package
• Part of the LM2576-compatible XH2576 regulator family

Applications

• Simple, high-efficiency step-down (buck) regulators
• On-board point-of-load 12V power conversion
• Efficient replacement for three-terminal linear regulators
• Industrial control and instrumentation power supplies
• Consumer and networking equipment power rails
• Battery-powered and 12V system power conversion

Why Source XH2576-12 from Pacific Component Xchange
