LTC3862EGN-2

DC DC Switching Controllers Overview

The LTC3862EGN-2#PBF is a two-phase, non-synchronous boost DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 5.5 V to 36 V and supports switching frequencies from 75 kHz to 500 kHz. The device utilizes peak current mode control with a fixed frequency architecture. It features clock synchronization capabilities via an external reference signal ranging from 50 kHz to 650 kHz. The controller includes a precision transconductance error amplifier for loop compensation and soft-start functionality. It is housed in a 24-pin SSOP package with exposed pad.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required gate drive voltage for the external MOSFETs. Confirm package availability and lead times through authorized distributors as supply status may vary.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring high efficiency at elevated output voltages. The two-phase topology reduces input and output ripple currents compared to single-phase designs. Verify that the external MOSFETs are compatible with the 10V gate drive requirements specified for this variant. Consider thermal management solutions suitable for the SSOP package.

DC DC Switching Controllers Part Context

This part belongs to the LTC3862 family of PolyPhase controllers designed for high-current boost applications.
