LT8310MPFE#TRPBF

Power Supply Controllers, Monitors Overview

The LT8310MPFE#TRPBF is a high-voltage synchronous buck controller from Analog Devices, designed for industrial and automotive applications. It operates with an input voltage range of 6V to 100V and supports output voltages down to 0.8V. The device features a fixed switching frequency of 500kHz and includes integrated bootstrap diode and driver circuitry. It offers precision current mode control with cycle-by-cycle current limiting and adjustable soft-start. The component is housed in a 20-lead TSSOP package with exposed paddle for thermal dissipation.
