The LT1913EDD#PBF is a 36V, 3.5A, 2.4MHz step-down switching regulator manufactured by Analog Devices. It is a series of current mode, step-down switching regulators providing 3.5A of continuous output current at selectable switching frequencies of 2.4MHz and 1.2MHz. It features reduced switching losses for reduced input ripple and improved efficiency. The device is based on a single synchronous buck regulator and is a low-cost solution for a broad variety of applications including telecom, industrial, and automotive. It features a high-side MOSFET current sense that extends operating input voltage up to 42V, making it suitable for automotive and industrial applications. The switching frequency of the device is adjustable for optimized efficiency and size, and can be synchronized for better EMI performance. It features an adjustable soft-start feature for optimally tailored application start-up, and has a low shutdown current of 0.01mA that enables the use of battery backup power. The LT1913EDD#PBF is ideal for applications where the best combination of efficiency, size, and cost are a requirement.
