LTC3703HGN#PBF Description

Short technical summary and product information.

The LTC3703HGN#PBF is a high voltage synchronous step-down switching regulator controller designed for applications requiring voltages up to 100V. It utilizes a constant frequency, voltage mode architecture to drive external N-channel MOSFETs.

 

Key features include a programmable operating frequency range of 100kHz to 600kHz, which can also be synchronized to an external clock. The controller boasts a precise internal reference with 1% DC accuracy and strong 1Ω gate drivers for driving multiple MOSFETs in higher current applications. It also offers programmable current limit, undervoltage lockout, and soft-start capabilities.

 

This device is suitable for demanding applications such as 48V telecom and base station power supplies, networking equipment, servers, and automotive and industrial control systems. The LTC3703HGN#PBF is available in a 16-pin SSOP package, designed for surface mounting.

 

Its architecture allows for efficient step-down conversion, with features like selectable pulse-skip mode operation and the elimination of a current sense resistor by utilizing the voltage drop across the synchronous MOSFET.
