LTC7813HUH#PBF

DC DC Switching Controllers Overview

The LTC7813HUH#PBF is a high-performance synchronous Boost+Buck DC/DC switching regulator controller manufactured by Analog Devices Inc. It drives all N-channel power MOSFET stages and contains independent step-up and step-down controllers. These can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that is above, below, or equal to the output voltage. The device supports an input voltage range of 8V to 60V. It features a fixed switching frequency of 850 kHz and operates with a maximum duty cycle of 100%. The controller provides an adjustable output voltage range from 800mV to 60V. It is housed in a QFN-32 package and is designed for non-isolated applications.

DC DC Switching Controllers Feature Summary

• Supports cascaded operation to regulate output voltages from inputs that are higher, lower, or equal to the output level
• Contains independent boost and buck controllers for dual-output regulation
• Drives all N-channel power MOSFET stages for synchronous conversion

DC DC Switching Controllers Applications

• Wide input range cascaded boost+buck regulators
