LT1172HVIQ High Efficiency Switching Regulator from Linear Technology

The LT1172HVIQ is a versatile and robust high-efficiency switching regulator from Linear Technology, designed to cater to a wide range of power supply applications. This product is part of the LT1172 series, which is well-known for its reliability and performance in demanding environments.

The LT1172HVIQ operates with an input voltage range from 3V to 60V, making it suitable for applications that require a wide input voltage capability. This feature is particularly beneficial for systems that experience large fluctuations in power supply or need to be compatible with various power sources.

One of the standout features of the LT1172HVIQ is its high switching frequency of up to 100kHz, which allows for smaller external components. This means that designers can use smaller inductors and capacitors, reducing the overall size and cost of the power supply without sacrificing performance. Additionally, the high frequency enables faster transient response, a critical factor in many power-sensitive applications.

The LT1172HVIQ also boasts a high efficiency of up to 85%, minimizing power loss and heat generation. This efficiency is achieved through the use of a 1.25A current limit, which is built into the device to protect against overcurrent conditions. The regulator also features a low dropout voltage, ensuring consistent performance even when the input voltage is close to the output voltage.

With its built-in catch diode, the LT1172HVIQ simplifies the circuit design and reduces external component count, further enhancing its appeal for compact and cost-effective power supply solutions. Moreover, the regulator is designed with thermal shutdown and a current limit to protect the device under abnormal operating conditions, ensuring long-term reliability and safety.

The LT1172HVIQ is available in a rugged metal can package, which provides excellent thermal performance and is suitable for harsh industrial environments. This makes it an ideal choice for applications such as automotive, telecommunications, and industrial control systems, where durability and consistent operation are critical.

In conclusion, the LT1172HVIQ from Linear Technology is a high-quality, high-efficiency switching regulator that offers exceptional performance, versatility, and reliability for a wide array of power supply applications.
