The LTC3417EFE#PBF is a monolithic synchronous DC/DC converter designed to power loads in excess of 2A, up to 3.6V, from a 3.6V to 28V input. Its high efficiency and small solution size make it ideal for space-constrained applications. It is available in a 5-lead SOT-23 package.

The LTC3417EFE#PBF belongs to the DC/DC switching regulator category of power management ICs (PMICs). These are specially designed circuits that regulate the output voltage and current of the device within specific limits, thus ensuring higher stability and accuracy in the output. The LTC3417EFE#PBF operates in such a manner that it optimizes efficiency without compromising the output voltage quality, resulting in a clean and stable output that can power many digital circuits.

The LTC3417EFE#PBF uses a synchronous buck topology, where the buck regulator is driven by a constant frequency, current-mode control. This allows for tight regulation of the output and fast transient response, making it ideal for use in high-current applications and in those that require high output accuracy. Additionally, the LTC3417EFE#PBF can deliver up to 3A for a 24V input and 2A for a 3.6V input.

The LTC3417EFE#PBF includes a number of features that make it an ideal choice for many applications. These include Integrated Power MOSFETs, enabling higher efficiency and lower power dissipation, adjustable Soft-Start and Shutdown controls, allowing the user to maintain desired output voltage during start and stop conditions, adjustable Frequency Foldback, which minimizes ripple in cases of high current draw, and Cycle-by-Cycle Current Limit, which prevents the device from exceeding a predetermined current level. The device also features Undervoltage Lockout and Overvoltage Protection, which ensures that the device is only active within the specified voltage range.

The LTC3417EFE#PBF is ideal for applications such as RF power amplifiers, cellular and cordless phone subsystems, and automotive systems. Its wide input voltage range, high efficiency and integrated protections make it well-suited for these types of applications.
