Introduction

Hi926X is a high-voltage, high-current output asynchronous buck DC-DC controller with fast dynamic response capability, featuring a wide input voltage range of 6–150V and reliable performance. Employing a patented algorithm control scheme, it achieves fast dynamic response while balancing the demands of transient performance and output voltage ripple, delivering rapid dynamic response with low output ripple. An integrated random sequence coded spread-spectrum function optimizes EMI. Suitable for high-performance industrial control, robotics, data communications, RF, and other applications. The adjustable current sensing reference significantly reduces CS sense resistor power loss. Cycle-by-cycle current limiting is externally adjustable for flexibility and convenience, with no external loop compensation required, simplifying system design and improving reliability. Supports over-temperature protection, output short-circuit protection, undervoltage protection, and soft-start functionality for safe and reliable operation.
