The LT8614IUDC#PBF is a DC-DC switching power regulator from Linear Technology Corporation and is part of the company’s LT8614 series of high output current, high efficiency DC-DC power regulators. Designed for space efficiency and high input voltage requirements, this cost effective power regulator is specifically intended for automotive, industrial, and high-end computing applications.

The LT8614IUDC#PBF offers high efficiency power conversion performance in a resilient 8-pin package. Its core features include a high output current of up to 10A, low quiescent current of 8µA and 100µA in standby mode, ultra-low on-resistance of 5.5mΩ, and programmable 60V and 80V input voltage range. The device has an adjustable voltage range of 3.8V to 16V for output, and is capable of transient response in under 500µS.

The LT8614IUDC#PBF is a synchronous step down regulator, with integrated NFET and PFET power switches. It operates in either a PFM Mode, or PWM Mode, which can be programmed to optimize the performance as needed. The device also has two modes of operation, Burst Mode and Speed Mode. The Speed Mode enables lower input current and higher quiescent current in order to achieve higher-efficiency operation at light load conditions, while Burst Mode enables the device to enter a low-power state and preserve battery life during heavier load conditions.

The LT8614IUDC#PBF has four protection circuits which helps protect the device from a wide range of common application faults. These protection circuits limit the voltage peaks due to capacitor leakage, or the output current when the inductor saturates. Additionally, it features cycle-by-cycle overcurrent protection and thermal shutdown protection, protecting both the device and the connected equipment against short-circuits.

Overall, the LT8614IUDC#PBF is an effective DC-DC switching power regulator, designed with automotive, industrial, and high-end computing applications in mind. It is capable of providing high output currents, low quiescent current in standby mode, and features various programmable features and protection circuits which help to ensure device stability and reliability.
