LT3480EDD#TRPBF - Low EMI, 36V, 2A Step-Down Regulator with 2.5µA Quiescent Current

The LT3480EDD#TRPBF is a compact, high-efficiency, step-down DC/DC converter from Linear Technology, designed to meet the needs of a wide range of applications requiring a reliable power supply solution. This versatile component is capable of delivering up to 2A of continuous output current with a wide input voltage range from 3.6V to 36V, making it suitable for systems that are subjected to large input voltage variations such as automotive and industrial applications.

One of the standout features of the LT3480EDD#TRPBF is its ultra-low quiescent current of only 2.5µA, which helps to maximize battery life in portable and battery-powered devices. This low quiescent current, combined with a high efficiency of up to 85%, ensures that the device operates with minimal power loss, making it an excellent choice for energy-sensitive applications.

The LT3480EDD#TRPBF is housed in a compact 10-lead (3mm x 3mm) DFN package, which is ideal for space-constrained environments. The device also includes a high efficiency switcher that utilizes a 3.3MHz constant frequency, current mode control scheme, providing excellent line and load regulation while minimizing the size of external components.

This step-down regulator incorporates several features to enhance its performance and ease of use, including a Burst Mode® operation that maintains high efficiency at low output currents, and a shutdown mode that reduces power consumption to less than 1µA. Additionally, the device has internal compensation and a soft-start feature that limits inrush current during startup, providing a smooth transition to regulation.

For protection and reliability, the LT3480EDD#TRPBF includes thermal shutdown, a power good flag, output overvoltage protection, and current limit protection. These features ensure that the device operates safely under a variety of conditions and protects both itself and the load from damage.

In summary, the LT3480EDD#TRPBF from Linear Technology is a highly efficient, low quiescent current step-down regulator that is well-suited for a wide array of applications that demand reliable power conversion with minimal power loss. Its compact size, robust protection features, and low EMI characteristics make it an excellent choice for designers looking to optimize their power supply design.
