The LT1317CMS8#PBF is a high-performance, low-noise step-up DC/DC converter designed by Linear Technology. It is housed in a compact MSOP-8 package, offering a space-efficient solution for a wide range of applications. This versatile component is well-suited for battery-powered devices due to its low quiescent current and high efficiency.
The device operates from an input voltage range of 2.7V to 15V, making it compatible with various power sources, including single-cell lithium-ion batteries. It can deliver a continuous output current up to 600mA with a selectable fixed frequency between 100kHz and 2MHz. This allows designers to optimize the converter for size by using smaller external components or for efficiency at a lower switching frequency.
The LT1317CMS8#PBF incorporates a 0.5Ω internal switch, enabling it to provide high current outputs with a minimal number of external components. Its current mode PWM architecture ensures stable operation over a wide range of supply and output voltages. Additionally, the device features a low-battery detector, which provides an early warning when the input supply falls below a preset threshold, ensuring reliable operation of the end application.
Safety and protection are also key aspects of the LT1317CMS8#PBF. It includes features such as thermal shutdown, which protects the device under excessive temperature conditions, and a current limit, which prevents damage from overcurrent conditions. The shutdown pin allows the device to be turned off, reducing the supply current to less than 1µA, which is particularly useful for preserving battery life in portable applications.
Whether employed in handheld medical devices, GPS units, portable media players, or other mobile applications, the LT1317CMS8#PBF from Linear Technology offers a robust, efficient, and compact power management solution that can be tailored to meet the specific needs of your design.
