The LTC3703IGN-5#TRPBF is a synchronous step-down switching regulator controller from LT, designed for high voltage applications up to 60V. This controller is ideal for telecom and automotive applications, driving external logic-level N-channel MOSFETs.
Key features include a programmable constant frequency ranging from 100kHz to 600kHz, which can also be synchronized to an external clock. It boasts a ±1% reference accuracy and strong 1Ω gate drivers for driving multiple MOSFETs in higher current applications. The device also offers selectable pulse skip mode operation and a low shutdown current of 25µA typical.
This controller utilizes a voltage mode architecture and eliminates the need for a current sense resistor by programming the current limit with an external resistor, using the voltage drop across the synchronous MOSFET. It is available in a 16-pin narrow SSOP package.
Applications include 48V telecom and base station power supplies, networking equipment, servers, and automotive and industrial control systems.
The input voltage range is from 6V to 60V.
The programmable constant frequency range is 100kHz to 600kHz.
