LTC1516CS8 Step-Up DC/DC Converter

The LTC1516CS8 is a highly efficient and versatile step-up DC/DC converter designed and manufactured by Linear Technology, now part of Analog Devices. This compact, monolithic device is capable of delivering a fixed output voltage of 5V or an adjustable output from 5V to 34V, making it an ideal choice for a wide range of applications, from battery-powered devices to industrial systems.

The LTC1516CS8 operates with an input voltage range of 1.5V to 10V, allowing it to be used with various low voltage power sources including single or multiple battery cells. Its low start-up voltage of just 1.5V and high switching frequency of 100kHz enable the use of small, cost-effective inductors and capacitors, thus minimizing the overall footprint and cost of the power supply design.

One of the standout features of the LTC1516CS8 is its high efficiency, which can reach up to 90%. This is achieved through the use of a low quiescent current and the integration of a low-resistance N-channel MOSFET switch. The high efficiency of this converter ensures minimal heat generation and extends battery life in portable applications.

The LTC1516CS8 also includes several protective features to ensure reliable operation. These include thermal shutdown, which protects the device from overheating, and a current limit function that prevents damage due to overcurrent conditions. Additionally, the converter features a low-battery detector that can be programmed to indicate when the input voltage falls below a certain threshold, alerting the user to a potential power failure.

Available in an 8-lead SOIC package, the LTC1516CS8 is designed for easy implementation into existing designs. Its small size and surface-mount package make it an excellent choice for space-constrained applications.

Whether you are designing a handheld device, a portable medical instrument, or an industrial control system, the LTC1516CS8 offers a robust and efficient solution for your step-up voltage conversion needs.
