TPS92513HV – TEXAS INSTRUMENTS

The TPS92513HV is a high-voltage, synchronous step-down converter from Texas Instruments, optimized for applications requiring efficient power conversion at elevated input voltages. Specifically designed for 12V to 75V input ranges, it delivers a regulated output voltage with a wide adjustable range (typically 3.3V to 30V), making it suitable for a variety of industrial and automotive applications. Its synchronous topology minimizes power loss, achieving high efficiency even at light loads, typically exceeding 95% in optimal conditions. The device features integrated high-side and low-side MOSFETs, eliminating the need for external switching elements and simplifying the bill of materials. Packaged in a space-saving 16-pin QFN package (4x4mm), it’s well-suited for compact designs. Key features include programmable switching frequency (up to 1MHz), soft-start functionality to minimize inrush current, and overcurrent protection for enhanced reliability. The TPS92513HV’s advantages lie in its high-voltage input capability, compact size, high efficiency, and integrated protection features, making it ideal for powering distributed power architectures in industrial control systems, automotive lighting, and high-voltage battery-powered equipment where space and efficiency are paramount.
