XH2596-ADJ – DC-DC Converter – Xinluda

The XH2596-ADJ from Xinluda is a 3A adjustable step-down (buck) switching regulator with a 1.2V-37V output range and 150kHz fixed-frequency operation, supplied in a TO-263 surface-mount package.

The XH2596-ADJ is a monolithic step-down (buck) switching voltage regulator from Xinluda Information Technology Co., Ltd. Part of the popular XH2596 SIMPLE SWITCHER-class family, the adjustable (ADJ) version integrates all of the active functions needed for a high-efficiency step-down converter capable of driving a 3A load with good line and load regulation. It is a function-compatible alternative to the industry-standard LM2596 architecture, making it a practical option for cost-sensitive power-supply designs.

Key Features

• Adjustable output voltage range of 1.2V to 37V (±4% maximum over line and load conditions)
• Up to 3A output load current
• Input voltage range up to 40V
• 150kHz fixed-frequency internal oscillator, allowing smaller external filter components
• Requires only four external components for a complete converter
• High-efficiency monolithic step-down (buck) topology
• TTL-compatible shutdown control with low-power standby mode (standby current typically 80µA)
• Built-in thermal shutdown and current-limit protection
• Uses readily available standard inductors
• Supplied in TO-263-5 surface-mount package (also offered in TO-220)

Applications

• On-board point-of-load step-down conversion for industrial and consumer electronics
• Simple, efficient replacement for linear regulators
• Battery and adapter-powered systems requiring regulated rails
• LED lighting and driver supplies
• Networking, set-top box, and embedded system power
• Distributed power architectures and pre-regulators
