LTC3775EMSE Description

Short technical summary and product information.

The LTC3775EMSE is a high efficiency synchronous step-down switching DC-DC controller manufactured by Linear Technology/Analog Devices. It is designed to drive all N-channel MOSFETs and operates in voltage mode control.

Key electrical specifications include a wide input voltage range from 4.5V to 38V, a programmable switching frequency from 250kHz to 1MHz, and a maximum duty cycle of 90%. It features powerful onboard MOSFET drivers, line feedforward compensation, and a low minimum on-time. The controller offers ±0.75% reference voltage accuracy over temperature and supports an output voltage range of 0.6V to 0.8VIN.

This controller supports cycle-by-cycle peak current limit sensing via a sense resistor or RDS(ON). It also includes programmable soft-start and synchronizable fixed frequency operation. The device can operate in selectable pulse-skipping or forced continuous modes. It has a low shutdown current of 14µA typical.

The LTC3775EMSE is available in a thermally enhanced 16-lead MSOP package (16-MSOP-EP) and a 3mm x 3mm QFN package. It is suitable for various step-down DC-DC conversion applications requiring high efficiency and precise voltage regulation.
