TEXAS INSTRUMENTS Adjustable DC-DC Step Down Regulator, 9.5-95V In, 2.5-75V Out

The TEXAS INSTRUMENTS Adjustable DC-DC Step Down Regulator is a high-performance switching regulator designed to efficiently convert a high input voltage down to a lower, stable output voltage. It features a wide input voltage range from 9.5V to 95V, making it suitable for a diverse array of applications, from industrial systems to automotive and telecommunications equipment.

This compact, surface-mount device delivers an adjustable output from 2.5V up to 75V with a maximum continuous output current of 350mA. Its buck (step-down) topology, combined with a high switching frequency of 600kHz, allows for the use of smaller external components, enabling a more compact and efficient overall power supply design.

Key Features & Applications

• Wide Input Range: Handles inputs from 9.5V to 95V, ideal for systems with fluctuating or high-voltage power sources like 24V/48V industrial buses or automotive systems.
• Adjustable Output: Provides flexible voltage regulation from 2.5V to 75V, perfect for powering microcontrollers, sensors, and other low-voltage circuits from a higher supply rail.
• High-Efficiency Design: The 600kHz switching frequency optimises performance and reduces the size of necessary inductors and capacitors.
• Robust Operation: With an operating temperature range of -40°C to 125°C, this regulator is built to perform reliably in harsh environmental conditions.
• Compact Package: Housed in an 8-pin VSSOP (MSOP-8) package, it is designed for space-constrained applications on printed circuit boards (PCBs).

This regulator is an essential component for engineers and hobbyists needing a reliable, efficient, and versatile voltage conversion solution for advanced electronic projects.
