LTC1700EMS Description

Short technical summary and product information.

The LTC1700EMS is a current mode synchronous step-up DC/DC controller manufactured by LT. It drives external N-channel and P-channel power MOSFETs using a constant frequency PWM architecture. A key feature is its No RSENSETM technique, which provides current limiting by sensing the voltage drop across the main MOSFET, eliminating the need for a sense resistor. This design helps maintain high efficiency at heavy loads.

 

This controller operates at a fixed frequency of 550 kHz, with a sync range from 400kHz to 750kHz. It supports synchronous rectification for high efficiency and features Burst Mode operation for improved efficiency at light loads. The device has a maximum switch current of 6A and can operate with an input voltage range of 2.34V to 5V, with a startup voltage as low as 0.9V. The maximum output voltage is 6V.

 

The LTC1700EMS is housed in an MS-10 package. It has a shutdown current of 10 µA and a supply current of 0.536 mA. The operating temperature range is from 0°C to 85°C. This controller is suitable for applications requiring efficient voltage step-up conversion.
