XH2596-12 – DC-DC Converter – Xinluda

The XH2596-12 from Xinluda is a fixed 12V output step-down (buck) switching regulator rated for 3A load current in a TO-263-5 surface-mount package. Available for RFQ from Pacific Component Xchange.

The XH2596-12 is a monolithic step-down (buck) switching voltage regulator from Xinluda, part of the XH2596 series. It integrates all the active functions required for a high-efficiency step-down switching regulator, delivering a fixed 12V output and capable of driving loads up to 3A with excellent line and load regulation. The device requires only a minimal number of external components, simplifying board design and reducing bill-of-material cost.

Built around a 150kHz fixed-frequency internal oscillator, the XH2596-12 allows the use of smaller, lower-cost filter components than lower-frequency switching regulators would require. Integrated protection features include cycle-by-cycle current limiting and thermal shutdown, making it a robust choice for industrial and consumer power-supply designs. The XH2596 series is offered in TO-220 and TO-263 packages; the XH2596-12 listed here is the surface-mount TO-263-5 (D2PAK) variant.

Key Features

• Fixed 12V output (XH2596-12 variant of the XH2596 3.3V / 5V / 12V / ADJ family)

• 150kHz fixed-frequency internal oscillator
• +/-4% output voltage tolerance over line and load conditions
• +/-15% tolerance on oscillator frequency
• External shutdown capability with typical 80uA standby current
• Current limiting via two-stage frequency reduction and thermal shutdown protection
• Requires only four external components
• TO-263-5 surface-mount package

Applications

• Simple, high-efficiency step-down (buck) regulators
